View IS-IS Accept Policy Information

1. Display IS-IS accept policy information:

   show ip isis accept [vrf WORD<1–16>][vrfids WORD<0–512>]

2. Display I-SID list information:

   show ip isid-list [vrf WORD<1–16>][vrfids WORD<0–512>][WORD<1–32>]

3. Display route information:

   show ip route [vrf WORD<1–16>]

   The NH VRF/ISID column displays the I-SID for inter-Virtual Services Network (VSN) routes redistributed with IS-IS accept policies, only if the I-SID redistributed does not have an IP VSN associated with it. If an IP VSN exists for that I-SID, the VRF name displays. If the I-SID is 0, the column represents and displays as the GlobalRouter.

   The existing IS-IS routes for Layer 3 VSNs continue to display as the VRF name of the IP VSN.

4. Display the SPBM IP unicast Forwarding Information Base (FIB):

   show isis spbm ip-unicast-fib [all] [id <1–16777215>][spbm-nh-as-mac] [home|remote]
