Routing Information Base
Each MT belongs to a Distinct Address Family and routes learned within that topology are installed in a separate Routing
Information Base (RIB). The RIB associated with MT IPv4 (ID#0) is the default IPv4 VRF.
Displaying Active IPv4 Routes
To display all active IPv4 routes in this RIB, use the following command:
show ip route isis
Note: Be aware this can be an extremely large output.
The C4/c CMTS displays an output similar to the following:
Codes: (L1) internal level-1, (L2) internal level-2, (eL1) external level-1, (eL2) external level-2
(S) summary, (IA) internal area, (E1) external type-1, (E2) external type-2
(I) internal, (E) external

Displaying Active IPv6 Routes
To display all active IPv6 routes in the RIB associated with the IPv6 (MT#2), use the following command:
show ipv6 route isis
Note: Be aware this can be an extremely large output.
The C4/c CMTS displays an output similar to the following:
Codes: (L1) internal level-1, (L2) internal level-2, (eL1) external level-1,
(eL2) external level-2 (S) summary, (IA) inter-area,
