Cisco Multiservice Switching Networks

It's time to reintroduce one of the most helpful show commands in the LSC (see Example 6-74) because it provides a global picture of the LSR state.

Example 6-74. Using the Command show mpls atm-ldp summary

P3_LSC_m8850_RPM-PR_9#show mpls atm-ldp summary Total number of destinations: 9 ATM label bindings summary interface total active local remote Bwait Rwait IFwait XTagATM101 16 16 8 8 0 0 0 XTagATM1111 16 16 8 8 0 0 0 XTagATM1144 36 36 18 18 0 0 0 P3_LSC_m8850_RPM-PR_9#

We can also calculate the number of LVCs that traverse each link following the previous reasoning.

XTagATM1144 has three eLSR-behaving routers on one side and six on the other side:

LVCs = 2 * 3 * 6 = 36

XTagATM101 and 1111 have one eLSR on one side and eight eLSR-behaving LSCs and eLSRs:

LVCs = 2 * 1 * 8 = 16

It is also interesting to observe the LDP negotiated capabilities (see Example 6-75) that were discussed in the section "LDP Session, Bindings, and LVC show Commands."

Example 6-75. Showing the LDP ATM Capabilities

The procedure to bring up the remaining P-P links is equivalent to what we already did, so we will not include the captures. At this point, our MPLS network is complete.
