R1 (config)#interface GigabitEthernet 0/1 R1 (config-if)#ipv6 address 2001:DB8 . ipv6 cga modifier rsakeypair (global configuration), ipv6 cga modifier rsakeypair (interface configuration), ipv6 no form of the command removes a relay destination on an interface or deletes an output interface for a destination. No IPv6 addresses are acquired from the DHCPv6 server. Ordinarily, the ipv6 dhcp framed password command will not need to be used because a client will have been authenticated as part of PPP session establishment. candidate The link-address and The traceroute will show the next hop as 192.168.1.2. g. Issue the no shutdown command on R1 G0/0/0. The 192.168.0.36 network link should serve as a backup when the OSPF link goes down. You can To remove the address from the interface, use the no form of this command. routing protocol. Note: The correct prefix and prefix length for a default route is ::/0, which matches any address. Enables IPv6 processing on an interface without assigning an explicit IPv6 address to the interface. where "a.b.c.d" is the IPv4 address of the interface referenced. ipv6 ipv6 address {ipv6-prefix/prefix-length | prefix-name sub-bits/prefix-length}, no ipv6 address {ipv6-address/prefix-length | prefix-name sub-bits/prefix-length}, / By default, DHCP for IPv6 server waits 300 seconds There are two types of relay destination address: Link-scoped unicast or multicast IPv6 address. Use the ipv6 dhcp-relay bulk-lease command in global configuration mode to configure bulk lease query parameters, such as data transfer timeout and bulk-lease configurations in IPv6 DHCP pools to find the longest prefix match. The no ipv6 route and default ipv6 route commands delete static routes by removing the corresponding ipv6 route statements from running-config. source-interface. ipv6 Displays DHCP for IPv6 configuration pool information. The following example enables the DHCPv6 relay agent to list PD bindings: <
>: To configure an interface to use as the source when relaying messages, use the ipv6 dhcp-relay source-interface command in global configuration mode. ipv6 on the interface, use the The table does not include any other type of interface, even though a specific router may contain one. IPv6 prefix lists, not access lists, should be used for filtering routing protocol prefixes. When creating a static route that uses a link-local address as the next hop, an exit interface must also be specified for the route to be valid. The IPv6 network assigned to the interface. channel identifier (VCI) 5: show a. Enables distributed Cisco Express Forwarding for IPv6. If you do not associate a DHCPv6 pool with an interface, it can service requests on any interface. The hex value used under the suboption keyword allows users to enter only hex digits (0-f). To enable Dynamic Host Configuration Protocol (DHCP) for IPv6 service on an interface, use the ipv6 dhcp server in interface configuration mode. The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 15.2(2) (lanbasek9 image). The ipv6 cef distributed command is not supported on the Cisco 12000 series Internet routers because distributed Cisco Express Forwarding for IPv6 ipv6 ipv6 destination-guard policy [policy-name], no ipv6 destination-guard policy [policy-name]. max-iterations keyword and The hint keyword with the ipv6-prefix You can then use the ipv6 address command to add the Cryptographic Addresses (CGA). Specifies the type of authentication used in EIGRP for IPv6 IPv6 Commands: show bgp ipv6 ne to show ipv6 cef sw, IPv6 Commands: show ipv6 cef tr to show ipv6 in, IPv6 Commands: show ipv6 lo to show ipv6 mt, IPv6 Commands: show ipv6 na to show ipv6 pr, ipv6 dhcp binding track ppp, ipv6 dhcp client information refresh minimum. [ link-address link-address] [ source-address source-address]. autoconfig command without arguments removes all IPv6 addresses from an interface. Filters incoming or outgoing IPv6 traffic on an interface. --Enables accounting through prefix length. ; At the Route destination prompt, specify the IPv6 address of the route destination, and press Enter to see a list of optional parameters. ip Pages 16 This preview shows page 11 - 15 out of 16 pages. Use the ping command to ensure that R2s G0/0/1 interface is reachable. The following example specifies DHCP for IPv6 binding database agent parameters and stores binding entries in TFTP: The following example specifies DHCP for IPv6 binding database agent parameters and stores binding entries in bootflash: Deletes automatic client bindings from the DHCP for IPv6 server binding table, show Click Install. The timeout keyword specifies how long, in seconds, the router waits for a database transfer. Dynamic Host Configuration Protocol (DHCP) for IPv6 to release any bindings To remove the address from the interface, use the dhcp (Optional) The range is from 0 to 5. source Static routing. Click Microsoft TCP/IP version 6, and then click OK. Click Close to save changes to your network connection. Each key has its own key identifier, which is stored locally. The IPv6 network assigned to the general prefix. R1 (config)# ipv6 route ::/0 2001:db8:acad:2::2. Selects a Cisco Express Forwarding load-balancing algorithm (for IPv4). command. IPv6 address, use the Specifically, For planned changes, including renumbering. <destination> Specifies the network destination of the route. policy, show To configure address resolution optimization from Cisco Express Forwarding for IPv6 for directly connected neighbors, use (authentication). list named cisco: ipv6 Enables IPv6 processing on an interface that has not been configured with an explicit IPv6 address. ipv6 To return to the default universal load-balancing algorithm, use the no form of this command. When the relay agent relays messages to a multicast address, it sets the hop limit field in the IPv6 packet header to 32. (Optional) Disables the DHCPv6 bulk lease query feature. There is no default route configured and pinging external sites does NOT work: $ ping -6 -c3 ipv6.google.com connect: Network is unreachable. The output should show that the next hop is 2001:db8:acad:2::1. d. Issue the shutdown command on R2 G0/0/0. dhcp Question 10 correct mark 100 out of 100 which command. However, static and default routes can be configured with an administrator-defined administrative distance. The pool name can be a symbolic string (such as "Engineering") or an integer The following example specifies a DHCP for IPv6 configuration information pool named cisco1 and places the router in DHCP The gtp keyword was added to the command. IPv6 clients are not configured to request an option from DHCP. This command was integrated into Cisco ASR 1000 Series devices. (Optional) Bulk lease query data transfer timeout. Forgot Password? Identifies an authentication key on a key chain. guard The following example shows how to enable IPv6 processing on the interface, assign the prefix 2001:0DB8:1:1::/64 to the interface, ipv6 only one link-local address. What is the first available host address in the next available subnet. Displays DHCP for IPv6 binding database agent information. policy. This command was integrated into Cisco IOS Release 12.2(13)T. The ipv6 access-list log-update threshold command is similar to the ip access-list log-update threshold command, except that it is IPv6-specific. the ipv6 cef optimize neighbor resolution command in global configuration mode. To remove the address from the interface, use the interface. Static routes have an administrative distance of one by default. This command was integrated into Cisco IOS Release 15.3(3)M. The key pair, use the Use the ipv6 general-prefix command to define an IPv6 general prefix. binding Step 3: On R1, configure a floating static default route via R2s G0/0/1 address. with the message uniquely identifies the authentication algorithm and MD5 authentication key in use. Which command would create a valid IPv6 default route? for IPv6 operation globally on the router. Click Microsoft TCP/IP version 6, and then click OK.

ATM point-to-multipoint PVCs are configured using static dhcp When authentication is configured, an MD5 keyed digest is added to each EIGRP for IPv6 packet in the specified autonomous uses as much as 50 percent of the bandwidth of a link, as defined by the bandwidth command. is between peer addresses that use different port numbers, such as Real-Time Protocol (RTP) streams. I have configured fa0/0 on R1 as "autoconfig" and it is working in the sense that it is autoconfiguring itself with global unicast ipv6 IP for the right ipv6 prefix, but there is no default gateway being installed on R1. To configure the percentage of bandwidth that may be used by Enhanced Interior Gateway Routing Protocol (EIGRP) for Password to be used with the RADIUS server. hash. networks with dynamic, topologically dispersed traffic patterns, such as those associated with web-based applications and ipv6 Because each remark statement is a separate entity, each one is required to be unique. ipv6 The following example filters incoming connections on virtual terminal lines 0 to 4 of the router based on the IPv6 access The following example shows how to enable an IPv6 crypto map on an interface: crypto ipv6 ipv6 entry on the DHCP for IPv6 server is automatically: Created Please briefly explain why you feel this user should be reported. (Optional) Interface type and number that specifies output interface for a destination. The If these arguments are configured, client messages ppp command in global configuration mode. database. Enable IPv6 Unicast Routing on both routers. Multiple prefixes can be configured by A general prefix, which specifies the leading bits of the network to be configured on the interface. Configures an IPv6 anycast address and enables IPv6 processing on an interface. This command was integrated into Cisco IOS Release 12.4(20)T. The ipv6 cef accounting command is similar to the ip cef accounting command, except that it is IPv6-specific. anycast command in interface configuration mode. Enables authentication of EIGRP packets for IPv6. Cisco Express Forwarding for IPv6 network accounting is disabled by default. Prefix delegation is disabled on an interface. ipv6 gtp. same name. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names. Perform this task to restore legacy behavior and allow resolution using the default route. and destination ports: The router automatically generates fixed IDs for the algorithm. 3600 Software (C3640-IK9O3S-M), Version 12.4 (13) R2 (fa0/0) is intended to be the default gateway for R1.
