routes advertised by the PE
into IS-IS.
6. Return to system view.
7. Enter interface view.
8. Enable the IS-IS process on
the interface.
Configuring EBGP between an MCE and a VPN site
To run EBGP between an MCE and a VPN site, you must configure a BGP peer for each VPN
instance on the MCE, and redistribute the IGP routes of each VPN instance on the VPN site.
1. Configure the MCE:
Step
1. Enter system view.
2. Enter BGP instance view.
3. Enter BGP-VPN instance
view.
4. Configure an EBGP peer.
5. Enter BGP-VPN IPv4
unicast address family
view.
6. Enable BGP to exchange
IPv4 unicast routes with
the peer.
7. Allow the local AS
number to appear in the
AS_PATH attribute of
routes received from the
peer, and set the
maximum number of
repetitions.
8. Redistribute remote site
routes advertised by the
PE into BGP.
2. Configure a VPN site:

Remarks
By default, IS-IS does not
redistribute routes from any other
routing protocol.
If you do not specify the route
level in the command, the
command redistributes routes to
the level-2 routing table by
default.
N/A
N/A
By default, no IS-IS process is
enabled on the interface.
Remarks
N/A
By default, BGP is not
enabled.
Configuration commands in
BGP-VPN instance view are
the same as those in BGP
instance view. For more
information, see Layer 3—IP
Routing Configuration Guide.
By default, no BGP peers or
peer groups exist.
N/A
By default, BGP does not
exchange IPv4 unicast routes
with any peer.
By default, BGP discards
incoming route updates that
contain the local AS number.
By default, no routes are
redistributed into BGP.
