Kompella supports three inter-AS implementations namely, virtual router and forwarder
(VRF)-to-VRF, multihop, and MP-EBGP. Martini and SVC support the inter-AS both in the
VRF-to-VRF mode and the Multihop mode.

Notes
An LSR ID is similar to the Router ID. An LSR ID
actually specifies an address. By default, LDP uses this
address to establish an LDP session, so ensure the
accessibility of the route to it. There are two methods to
set an LSR ID.
• Ensure that the LSR-ID is unique in the backbone
network. The LSR ID is generally set to the address of
the loopback interface.
• If the mpls Idp transport-address command is
configured on the interface that connects to the public
network, LDP will use the address specified by this
command to establish an LDP session.
You need to enable MPLS in the system view
The dynamic VC connection uses the LDP as the
signaling.
If PEs do not connect directly, the remote MPLS LDP
session must be set up between PEs.
