With inter-AS MoFRR at the leaf, the leaf selects a primary ASBR and a backup ASBR. These ASBRs are disjointed ASBRs.
The primary and backup LSPs is set up using the primary and backup ASBRs, as illustrated in Figure 1.
Figure 1. ASBR MoFRR leaf behavior
Note: Using Figure 1 as a reference,
ensure that the paths to ASBR-1 and ASBR-2 are disjointed from
the leaf. MLDP does not support TE and cannot create two
disjointed LSPs from the leaf to ASBR-1 and ASBR-2. The operator
and IGP architect must define the disjointed paths.
