You can assign more NET addresses, but the System ID portion of the NET address must remain the same. Dell Networking OS
supports up to six area addresses.
Some address considerations are:
•
In order to be neighbors, configure Level 1 routers with at least one common area address.
•
A Level 2 router becomes a neighbor with another Level 2 router regardless of the area address configured. However, if the area
addresses are different, the link between the Level 2 routers is only at Level 2.
Configuring Multi-Topology IS-IS (MT IS-IS)
To configure multi-topology IS-IS (MT IS-IS), use the following commands.
1.
Enable multi-topology IS-IS for IPv6.
ROUTER ISIS AF IPV6 mode
multi-topology [transition]
Enter the keyword transition to allow an IS-IS IPv6 user to continue to use single-topology mode while upgrading to multi-
topology mode. After every router has been configured with the transition keyword, and all the routers are in MT IS-IS IPv6
mode, you can remove the transition keyword on each router.
NOTE: When you do not enable transition mode, you do not have IPv6 connectivity between routers operating in
single-topology mode and routers operating in multi-topology mode.
2.
Exclude this router from other router's SPF calculations.
ROUTER ISIS AF IPV6 mode
set-overload-bit
3.
Set the minimum interval between SPF calculations.
ROUTER ISIS AF IPV6 mode
spf-interval [level-l | level-2 | interval] [initial_wait_interval
[second_wait_interval]]
Use this command for IPv6 route computation only when you enable multi-topology. If using single-topology mode, to apply to
both IPv4 and IPv6 route computations, use the spf-interval command in CONFIG ROUTER ISIS mode.
4.
Implement a wide metric-style globally.
ROUTER ISIS AF IPV6 mode
isis ipv6 metric metric-value [level-1 | level-2 | level-1-2]
To configure wide or wide transition metric style, the cost can be between 0 and 16,777,215.
Configuring IS-IS Graceful Restart
To enable IS-IS graceful restart globally, use the following commands. Additionally, you can implement optional commands to enable
the graceful restart settings.
•
Enable graceful restart on ISIS processes.
ROUTER-ISIS mode
graceful-restart ietf
•
Configure the time during which the graceful restart attempt is prevented.
ROUTER-ISIS mode
