Configuration Guide - IP Routing
[RouterA-GigabitEthernet2/0/0] ip topology red enable
[RouterA-GigabitEthernet2/0/0] isis topology red
[RouterA-GigabitEthernet2/0/0] ipv6 topology blue enable
[RouterA-GigabitEthernet2/0/0] isis ipv6 topology blue
[RouterA-GigabitEthernet2/0/0] quit
Step 6 Verify the configuration
After the configuration is complete, run the display isis route command on the routers to view
information about the learned routes. The following example uses the display on Router D.
# Check the routing information on Router D.
[RouterD] display isis route
IPV6 Dest.
--------------------------------------------------------------------------
2008::/64
2001:db8:2::/64
2001:db8:1::/64
IPv6 routes are calculated only on the IPv6 topology. Therefore, the outbound interface of the
route from Router D to 2008::/64 is GE 2/0/0.
# Run the tracert command on Router D.
[RouterD] tracert ipv6 2008::1
traceroute to 2008::1
1 2008::1 62 ms
To make a comparison between the preceding routing information and the routing information
when an IPv4/IPv6 topology is deployed, run the following commands.
[RouterD] isis 1
[RouterD-isis-1] ipv6 enable
Configuration modifications on Router A and Router C are the same as that on Router D.
After the configuration is modified, run the display isis route command on the routers once
again to view information about the learned routes. The following example uses the display on
Router D.
# Check the routing information on Router D.
[RouterD] display isis route
IPV6 Dest.
--------------------------------------------------------------------------
2008::/64
2001:db8:2::/64
2001:db8:1::/64
The preceding output shows that the outbound interface of the route from Router D to 2008::/64
is GE 1/0/0. This is because in the SPF calculation when an IPv4/IPv6 topology is deployed, the
cost of the link passing through GE 1/0/0 to 2008::1/64 is smaller.
