Usage guidelines
To enhance stability of IPv6 BGP connections, HP recommends using a loopback interface as the source
interface for establishing a TCP connection.
To establish multiple BGP connections to a BGP router, specify on the local router the respective source
interfaces for establishing TCP connections to the peers on the peering BGP router. If you do not, the local
BGP router might fail to establish TCP connections to the peers when using the outbound interfaces of the
best routes as the source interfaces.
Examples
# Specify loopback 0 as the source interface for routing updates to peer 1:2::3:4.

peer default-route-advertise
Use peer default-route-advertise to advertise a default route to a peer/peer group.
Use undo peer default-route-advertise to disable advertising a default route.
Syntax
peer { group-name | ipv4-address | ipv6-address } default-route-advertise [ route-policy
route-policy-name ]
undo peer { group-name | ipv4-address | ipv6-address } default-route-advertise
Default
No default route is advertised to a peer/peer group.

Default command level
2: System level
Parameters
group-name: Name of an IPv4 or IPv6 peer group, a string of 1 to 47 characters.
ipv4-address: IPv4 address of a peer.
ipv6-address: IPv6 address of a peer.
route-policy-name: Name of a routing policy, a string of 1 to 63 characters.
Usage guidelines
Using this command does not require availability of the default route in the routing table. With this
command used, the router sends the default route unconditionally to the peer/peer group with the next
hop being itself.
Examples
# Advertise a default route to peer 1:2::3:4.
