PurposeCommand or Action
(Optional)
Verifies that the tunnel announces IPv6 autoroute
information.
show mpls traffic-eng autoroute
Example:
RP/0/RP0/CPU0:router#show mpls traffic-eng autoroute
Step 10
Destination 192.168.0.2 has 1 tunnels in IS-IS ring
level 1
tunnel-te1 (traffic share 0, nexthop 192.168.0.2)
(IPv4 unicast)
(IPv6 unicast)
(Optional) Verifies that the tunnel announces IPv6
forwarding adjacency information.
show mpls traffic-eng forwarding-adjacency
Example:
RP/0/RP0/CPU0:router#show mpls traffic-eng
Step 11
forwarding-adjacency
destination 3.3.3.3 has 1 tunnels
tunnel-te10 (traffic share 0,
next-hop 3.3.3.3)
(Adjacency Announced:
yes, holdtime 0)
(IS-IS 100, IPv4 unicast)
(IS-IS 100, IPv6 unicast)
Configuring Path-selection Cost Limit
Apply the path-selection cost-limit configuration to set the upper limit on the path aggregate admin-weight
when computing paths for MPLS-TE LSPs. Once the path-selection cost is configured, the periodic path
verification will check if the cost-limit is crossed. Path-selection cost limit can be configured at global MPLS
TE, per interface tunnel, and per path-option attribute set. The path-selection cost limit per path-option attribute
set takes the highest priority, followed by per interface and MPLS TE global path-selection cost limit values.
Configuring Global Path-selection Cost Limit on MPLS TE Tunnels
Perform these steps to configure path-selection cost limit globally for MPLS TE tunnels:
