Usage Guidelines

IS-IS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

If leaked subnet routes are present, that information displays in the output.

To view the status of management routes, use the show ip route vrf command and enter mgmt-vrf as follows. You must enter the name of the management VRF manually. Example output is shown below. 
device# show ip route vrf mgmt-vrf
IP Routing Table for VRF "mgmt-vrf"
Total number of IP routes: 3
'*' denotes best ucast next-hop
'[x/y]' denotes [preference/metric]

0.0.0.0/0
