Command Remarks
9. Advertise a default VPN route
to a peer or peer group.
peer { group-name | ip-address }
default-route-advertise
vpn-instance vpn-instance-name
Optional.
By default, no default VPN route is
advertised to a peer or peer group.
10. Apply an ACL to filter routes
received from or advertised to
a peer or peer group.
peer { group-name | ip-address }
filter-policy acl-number { export |
import }
Optional.
By default, no ACL-based filtering
is configured.
11. Save all route updates from a
peer or peer group.
peer { group-name | ip-address }
keep-all-routes
By default, BGP does not save
route updates from any peer.
12. Specify the router as the next
hop of routes sent to a peer or
peer group.
peer { group-name | ip-address }
next-hop-local
By default, the router sets itself as
the next hop for routes sent to an
EBGP peer or peer group, but it
does not change the next hop for
routes sent to an IBGP peer or peer
group.
13. Configure BGP to not change
the next hop of routes sent to
an EBGP peer or peer group.
peer { group-name | ip-address }
next-hop-invariable
Optional.
By default, the router sets itself as
the next hop for routes sent to an
EBGP peer or peer group.
In an inter-AS option C network
where an RR is used to advertise
VPNv4 routes, configure this
command on the RR so the RR does
not change the next hop of routes
sent to EBGP peers and clients.
14. Specify a preferred value for
routes received from a peer or
peer group.
peer { group-name | ip-address }
preferred-value value
Optional.
By default, the preferred value is 0.
15. Apply a prefix list to filter
routes received from or
advertised to a peer or peer
group.
peer { group-name | ip-address }
prefix-list prefix-list-name { export
| import }
By default, no prefix list based
filtering is configured.
16. Configure BGP updates
advertised to an EBGP peer or
peer group to carry only
public AS numbers.
peer { group-name | ip-address }
public-as-only
Optional.
By default, BGP route updates
advertised to an EBGP peer or peer
group can carry both public and
private AS numbers.
17. Configure the router as a route
reflector and specify a peer or
peer group as its client.
peer { group-name | ip-address }
reflect-client
By default, no RR is configured.
18. Specify the maximum number
of routes BGP can receive
from a peer or peer group.
peer { group-name | ip-address }
route-limit prefix-number
[ { alert-only | reconnect
reconnect-time } |
percentage-value ] *
By default, the number of routes
that BGP can receive from a peer
or peer group is not limited.
19. Apply a routing policy to a
peer or peer group.
peer { group-name | ip-address }
route-policy route-policy-name
{ export | import }
By default, no routing policy is
applied to a peer or peer group.
