Setup Guide

CONFIG-ROUTER-BGP mode
address-family ipv6 [unicast | vrf vrf-name]
unicast — Species the IPv6 unicast address family. The default address-family is IPv6 unicast.
vrf vrf-name — Species the name of VRF instance associated with the IPv6 address-family conguration.
• Enable the neighbor to exchange prexes for IPv6 unicast address family.
CONFIG-ROUTER-BGP-AF (Address Family) mode
neighbor {ip-address | ipv6–address | peer-group-name} activate
Example of conguring BGP Peers
DellEMC(conf)# router bgp 10
DellEMC(conf-router_bgp)# neighbor 2001::1 remote-as 200
DellEMC(conf-router_bgp)# neighbor 2001::1 no shutdown
DellEMC(conf-router_bgp)# address-family ipv6 unicast
DellEMC(conf-router_bgpv6_af)#neighbor 2001::1 activate
DellEMC(conf-router_bgpv6_af)#exit
Following is the output of show ip bgp ipv6 unicast summary command for the above conguration example.

Example-Conguring IPv4 and IPv6 neighbors
The following example congurations show how to enable BGP and set up some peer under IPv4 and IPv6 address families.
To support your own IP addresses, interfaces, names, and so on, you can copy and paste from these examples to your CLI. Be sure that you
make the necessary changes.

Example of enabling BGP and address family conguration in router (R1)
Following is an example to enable BGP and address family conguration for the neighbor R2 (20.20.20.2) in the router R1.
R1(conf)# router bgp 10
R1(conf-router_bgp)# neighbor 20.20.20.2 remote-as 200
R1(conf-router_bgp)# neighbor 20.20.20.2 no shutdown
R1(conf-router_bgp)# neighbor 2001::2 remote-as 200
R1(conf-router_bgp)# neighbor 2001::2 no shutdown
R1(conf-router_bgp)# neighbor 30.30.30.1 remote-as 20
R1(conf-router_bgp)# neighbor 30.30.30.1 no shutdown
R1(conf-router_bgp)# neighbor 3000::1 remote-as 300
R1(conf-router_bgp)# neighbor 3000::1 no shutdown
R1(conf-router_bgp)# no neighbor 3000::1 activate
R1(conf-router_bgp)# address-family ipv4 multicast
R1(conf-router_bgp_af)# neighbor 20.20.20.2 activate
R1(conf-router_bgp_af)# exit
R1(conf-router_bgp)# address-family ipv6 unicast
R1(conf-router_bgpv6_af)# neighbor 20.20.20.2 activate
R1(conf-router_bgpv6_af)# neighbor 2001::2 activate
R1(conf-router_bgpv6_af)#exit
