[j-nsp] ISIS Queries (ref-bw & L1 metric)

[Jking T]

Hi Experts,

I have couple of queries on IS-IS

1) Just wondering what reference-bandwidth value in "show isis overview" indicates?? 
We have set reference-bandwidth as 1000g for ISIS. (We dont see this output with routers not having reference-bandwidth command)

Lab at Mumbdst1> show isis overview 
Instance: master
  Router ID: x.x.x.x
  Adjacency holddown: enabled
  Maximum Areas: 3
  LSP life time: 65535
  Reference bandwidth: 3567587328  <<<---
  Attached bit evaluation: enabled
  SPF delay: 200 msec, SPF holddown: 5000 msec, SPF rapid runs: 3
  IPv4 is enabled, IPv6 is enabled
  Traffic engineering: enabled
  Restart: Enabled
    Restart duration: 200 sec
    Helper mode: Enabled
  Level 1
    Internal route preference: 15
    External route preference: 160
    Wide metrics are enabled, Narrow metrics are enabled
  Level 2
    Internal route preference: 18
    External route preference: 165
    Wide metrics are enabled

2) We have few routers in the setup & all in Level-2. (Level1 disabled). In that case, shouldnt we expect not to see Level1 Metric information in both the outputs???

Lab at Mumbdst1> show isis interface 
IS-IS interface database:
Interface             L CirID Level 1 DR        Level 2 DR        L1/L2 Metric
lo0.0                    0   0x1 Passive           Passive                 0/0
xe-0/0/0.0            2   0x1 Disabled          Point to Point        100/100000  
ge-1/0/0.0            2   0x1 Disabled          Point to Point        100/1000

Any thoughts??

Thank you.

Regards,
JK
