Remarks
8.
Filter routes received from or
advertised to a peer or peer
group based on an AS_PATH
list.
peer
{
group-name

aspath-filter-number
{
import
|
export
}
By default, no AS filtering list is
applied to a peer or peer group.
9.
Advertise a default VPN
route to a peer or peer group.
peer
{
group-name
|
ipv4-address
[
mask-length
] }
default-route-advertise
vpn-instance
vpn-instance-name
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
|
ipv4-address
[
mask-length
] }
filter-policy
ipv4
-
acl-number
{
export
|
import
}
By default, no ACL-based filtering
is configured.
11.
Save all route updates from a
peer or peer group.
peer
{
group-name

ip-address
[
mask-length
] }
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

the next hop for routes sent to a
peer or peer group.

Configure BGP to not
change the next hop of
routes sent to a BGP peer or
peer group.
peer

next-hop-invariable
By default, the router sets itself as
the next hop for routes sent to a
BGP 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 BGP peers and
clients.

19.
Set the maximum number of
