Sample Configurations

The following configurations are examples for enabling IPv6 IS-IS. These examples are not comprehensive directions. They are intended to
give you some guidance with typical configurations.
NOTE: Only one IS-IS process can run on the router, even if both IPv4 and IPv6 routing is being used.
You can copy and paste from these examples to your CLI. To support your own IP addresses, interfaces, names, and so on, be sure that you
make the necessary changes.
NOTE: Whenever you make IS-IS configuration changes, clear the IS-IS process (re-started) using the clear isis command.
The clear isis command must include the tag for the ISIS process. The following example shows the response from the
router:
Dell#clear isis *
% ISIS not enabled.
Dell#clear isis 9999 *
You can configure IPv6 IS-IS routes in one of the following three different methods:
• Congruent Topology — You must configure both IPv4 and IPv6 addresses on the interface. Enable the ip router isis and ipv6
router isis commands on the interface. Enable the wide-metrics parameter in router isis configuration mode.
• Multi-topology — You must configure the IPv6 address. Configuring the IPv4 address is optional. You must enable the ipv6 router
isis command on the interface. If you configure IPv4, also enable the router isis command. In router isis configuration mode,
enable multi-topology under address-family ipv6 unicast.
• Multi-topology Transition — You must configure the IPv6 address. Configuring the IPv4 address is optional. You must enable the
ipv6 router isis command on the interface. If you configure IPv4, also enable the ip router isis command. In router isis
configuration mode, enable multi-topology transition under address-family ipv6 unicast.
