(Optional.) Configure the PE
to not change the next hop of
routes advertised to the
EBGP peer.

Configure this command on the
RR so the RR does not change
the next hop of advertised VPNv4
routes.
Configuring an ASBR
To set up an inter-AS public tunnel for the inter-AS option C solution, an ASBR must assign an MPLS
label to the route destined for a PE, and advertise the label along with the route. Typically, the routes
advertised by an ASBR through BGP include the PE address as well as other routes. You can
configure a routing policy to filter routes. Routes surviving the filtering are assigned labels, and all
others are advertised as common IPv4 routes.
To configure a routing policy, use the following commands:
•
if-match
mpls-label
—Matches routes carrying MPLS labels.
•
apply
mpls-label
—Sets MPLS labels for IPv4 routes advertised to a peer. You can use this
command together with
if-match
clauses. For example, the
apply mpls-label
command works
together with the
if-match mpls-label
command to set new MPLS labels for routes with MPLS
labels. The newly assigned labels are advertised along with the routes.
