DellEMC(conf-router_bgpv6_af)# neighbor 10.1.1.2 activate
DellECM(conf-router_bgpv6_af)# exit
Conguring the auto-local-address for a neighbor will dynamically pick the local BGP interface IPv6 address (2001::1/64) as a the next hop
for all the updates over IPv4 neighbor congured under IPv6 address family. If the auto-local-address is not congured, the IPv4 mapped
IPv6 address (10.1.1.1) as a next hop.
Following is the show running-config command output for the above conguration.
DellEMC# show running-config bgp
!
router bgp 655
bgp router-id 1.1.1.1
neighbor 10.1.1.2 remote-as 20

Example conguration performed in R2
DellEMC# configure terminal
DellEMC(conf)# router bgp 20
DellEMC(conf-router_bgp)# neighbor 10.1.1.1 remote-as 655
DellEMC(conf-router_bgp)# neighbor 10.1.1.1 no shutdown
DellEMC(conf-router_bgp)# address-family ipv6 unicast
DellEMC(conf-router_bgpv6_af)# neighbor 10.1.1.1 activate
DellECM(conf-router_bgpv6_af)# exit
Following is the show running-config command output for the above conguration.
DellEMC# show running-config bgp

Following is the show ip bgp ipv6 unicast command output for the above conguration.
