Establishing Sessions with BGP Neighbors for Nondefault VRF
To establish sessions with either IPv6 or IPv4 BGP neighbors for nondefault VRFs, follow these steps:
1 Enable BFD globally.
CONFIGURATION mode
bfd enable
2 Specify the AS number and enter ROUTER BGP conīguration mode.
CONFIGURATION mode
router bgp as-number
3 Specify the address family as IPv4.
CONFIG-ROUTERBGP mode
address-family ipv4 vrf vrf-name
4 Add an IPv4 BGP neighbor or peer group in a remote AS.
CONFIG-ROUTERBGP_ADDRESSFAMILY mode
neighbor {ip-address | peer-group name} remote-as as-number
5 Enable the BGP neighbor.
CONFIG-ROUTERBGP_ADDRESSFAMILY mode
neighbor {ip-address | peer-group-name} no shutdown
6 Add an IPv6 BGP neighbor or peer group in a remote AS.
CONFIG-ROUTERBGP_ADDRESSFAMILY mode
neighbor {ipv6-address | peer-group name} remote-as as-number
7 Enable the BGP neighbor.
CONFIG-ROUTERBGP_ADDRESSFAMILY mode
neighbor { ipv6-address | peer-group-name} no shutdown
8 Specify the address family as IPv6.
CONFIG-ROUTERBGP_ADDRESSFAMILY mode
address-family ipv6 unicast vrf vrf-name
NOTE
: Before performing this step, create the required VRF.
