Configuring an LDP PW
Before you configure an LDP PW, enable global and interface MPLS LDP on the PE. For information
about MPLS LDP configuration, see "Configuring LDP."
To configure an LDP PW:
Step Command
Remarks
1.
Enter system view.

enter cross-connect PW
view.

] *
By default, no LDP PWs exist.
After an LDP PW is created, the
PE automatically sends a targeted
hello to create an LDP session to
the peer PE. Then, the PE
exchanges the PW ID FEC and
PW label mapping with the peer.
5.
Set the expected bandwidth
for the PW.
bandwidth
bandwidth-value
By default, the expected
bandwidth is 10000000 kbps.
Configuring a BGP PW
To configure a BGP PW, perform the following configurations on PEs:
•
Configure BGP to advertise MPLS L2VPN label block information.
•
Create a BGP PW.

4.
Create the BGP L2VPN
address family and enter BGP
L2VPN address family view.

By default, no BGP L2VPN
address family exists.
5.
Enable BGP to exchange BGP
L2VPN information with the
specified peer or peer group.
peer

By default, BGP cannot
exchange BGP L2VPN
information with any peer or
peer group.
6.
Enable BGP to exchange label
block information with the
specified peer or peer group.

By default, BGP can
exchange label block
information with a BGP
L2VPN peer or peer group by
using RFC 4761
MP_REACH_NLRI.
