Congure Dual Stack
OS10 supports dual stack for BGPv4 and BGPv6. Dual stack BGP allows simultaneous exchange of same IPv4 or IPv6 prexes through
dierent 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 prex information, it activates the IPv6 address-family. For a BGP-v6 neighbor to carry ipv4
prex, it activates the IPv4 address-family.
1 Enable support for the IPv6 unicast family in CONFIG-ROUTER-BGP mode.

2 Enable IPv6 unicast support on a BGP neighbor/template in CONFIG-ROUTER-BGP-AF mode.

Peer templates
To congure multiple BGP neighbors at one time, you can create and populate a BGP peer template. An advantage of conguring peer
templates is that members of a peer template inherit the conguration properties of the template and share update policy. Always create a
