Step
4. (Optional.) Redistribute
remote site routes advertised
by the PE.
5. Return to system view.
6. Enter interface view.
7. Enable the IS-IS process on
the interface.
For more information about IS-IS, see Layer 3—IP Routing Configuration Guide.
Configuring EBGP between an MCE and a VPN site
To use EBGP for exchanging routing information between an MCE and VPN sites, 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 sites.
1. Configure the MCE:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter BGP-VPN instance
view.
4. Specify an EBGP peer or
peer group.
5. Create and enter BGP-VPN
IPv4 unicast instance view.
6. Enable exchange of IPv4
unicast routes with the
specified peer or peer
group.
7. Allow routing loops: allow
the local AS number to
appear in the AS_PATH
attribute of routes received
from the peer or peer group
and specify the maximum
appearance times.
8. Redistribute remote site
routes advertised by the PE.

Remarks
By default, IS-IS does not
redistribute routes of 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.
