More show Commands


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
 P3_LSC_m8850_RPM-PR_9#show mpls atm-ldp capability                VPI           VCI           Alloc   Odd/Even VC Merge XTagATM101     Range         Range         Scheme  Scheme   IN   OUT   Negotiated   [0 - 0]       [33 - 3808]   BIDIR            -    -   Local        [0 - 0]       [33 - 3808]   BIDIR   EVEN     NO   NO   Peer         [0 - 0]       [33 - 65518]  UNIDIR  ODD      -    -                VPI           VCI           Alloc   Odd/Even VC Merge XTagATM1111    Range         Range         Scheme  Scheme   IN   OUT   Negotiated   [1 - 1]       [33 - 1018]   BIDIR            -    -   Local        [0 - 255]     [33 - 65535]  BIDIR   EVEN     NO   NO   Peer         [1 - 1]       [33 - 1018]   UNIDIR  ODD      -    -                VPI           VCI           Alloc   Odd/Even VC Merge XTagATM1144    Range         Range         Scheme  Scheme   IN OUT   Negotiated   [27 - 27]     [33 - 65535]  BIDIR            -  -   Local        [27 - 27]     [33 - 65535]  BIDIR   ODD      NO NO   Peer         [27 - 27]     [33 - 65535]  BIDIR   EVEN     -  - P3_LSC_m8850_RPM-PR_9# 

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.
