Dual stack BGP allows simultaneous exchange of same IPv4 or IPv6 prefixes through different IPv4 and IPv6 peers. You can enable dual stack using the activate command in the corresponding address-family mode. By default, activate command is enabled for the IPv4 address family for all the neighbors. If a BGP-v4 neighbor wants to carry ipv6 prefix information, it activates the IPv6 address-family. For a BGP-v6 neighbor to carry ipv4 prefix, it activates the IPv4 address-family. 1 Enable support for the IPv6 unicast family in CONFIG-ROUTER-BGP mode. address family ipv6 unicast 2 Enable IPv6 unicast support on a BGP neighbor/template in CONFIG-ROUTER-BGP-AF mode. activate Peer templates To configure multiple BGP neighbors at one time, create and populate a BGP peer template. An advantage of configuring peer templates is that members of a peer template inherit the configuration properties of the template and share update policy. Always create a peer template and assign a name to it before adding members to the peer template. Create a peer template before configuring any route policies for the template. 1 Enable BGP and assign the AS number to the local BGP speaker in CONFIGURATION mode, from 1 to 65535 for 2 byte, 1 to 4294967295 | 0.1 to 65535.65535 for 4 byte, or 0.1 to 65535.65535 in dotted format. router bgp as-number 2 Create a peer template by assigning a neighborhood name to it in ROUTER-BGP mode. template template-name 3 (Optional) Add a text description for the template in ROUTER-TEMPLATE mode. description text 4 Enter Address Family mode in ROUTER-NEIGHBOR mode. address-family {[ipv4 | ipv6] [unicast]} 5 Filter networks in routing updates, create a route-map and assign a filtering criteria in ROUTER-BGP-NEIGHBOR-AF mode. distribute-list prefix-list-name {in | out} route-map map-name {in | out} 6 Add a neighbor as a remote AS in ROUTER-TEMPLATE mode, from 1 to 65535 for 2 byte, 1 to 4294967295 | 0.1 to 65535.65535 for 4 byte, or 0.1 to 65535.65535 in dotted format. neighbor ip-address 7 Add a remote neighbor, and enter the AS number in ROUTER-TEMPLATE mode. remote-as as-number • To add an EBGP neighbor, configure the as-number parameter with a number different from the BGP as-number configured in the router bgp as-number command.
