Usage Guidelines

Usage Scenario

An SRLG, like the bandwidth and affinity attributes, is a constraint in TE path calculation. If an SRLG is configured for links, an IGP floods the TE link information along with the SRLG membership information to all devices in an IGP area. The SRLG membership information is then also added into the TEDB.

Precautions

MPLS TE-related commands apply only to MPLS TE and SR-MPLS TE. However, this command applies to SRv6 TE Policies, besides MPLS TE and SR-MPLS TE.

Example

# Add GE 0/1/0 to SRLG1 and SRLG2.

<HUAWEI> system-view
[~HUAWEI] te attribute enable
[*HUAWEI] interface GigabitEthernet 0/1/0
[*HUAWEI-GigabitEthernet0/1/0] te srlg 1
[*HUAWEI-GigabitEthernet0/1/0] te srlg 2
