To enable advertisement of IPv4 routes over IPv6 next hops selectively to an external BGP IPv6 peer, use the neighbor rfc5549-support command. This command may only be applied to external BGP peers via single hop.
| Default | RFC 5549 support is enabled by default for all neighbors. |
| Format | neighbor { ipv6-address | autodetect interface interface-name } rfc5549-support |
| Mode | BGP Router Config |
| Parameter | Description |
|---|---|
| ipv6-address | The neighbor's IPv6 address |
| autodetect interface interface-name | The routing interface on which the neighbor's link local IPv6 address is auto detected. |
Example:
(R1) # configure (R1) (Config) # router bgp 100 (R1) (Config-router) # neighbor 2001::2 rfc5549-support
