17. IS-IS

Time for some IS-IS routing! Between IS-IS and OSPF, those are the two most

coming SP core routing protocols.

RP/0/7/CPU0:R1#conf t

First we need to name our process

RP/0/7/CPU0:R1(config)#router isis LAB

Then configure our Network Entity ( Area )

RP/0/7/CPU0:R1(config-isis)#net 49.0000.0000.0001.00

Then we assign the interfaces to the process, as well as the address family.

RP/0/7/CPU0:R1(config-isis)#int l0

RP/0/7/CPU0:R1(config-isis-if)#address-family ipv4

RP/0/7/CPU0:R1(config-isis-if-af)#exit

RP/0/7/CPU0:R1(config-isis-if)#address-family ipv6

RP/0/7/CPU0:R1(config-isis-if-af)# exit

RP/0/7/CPU0:R1(config-isis-if)#int g0/3/0/2

RP/0/7/CPU0:R1(config-isis-if)#address-family ipv4

RP/0/7/CPU0:R1(config-isis-if-af)# exit

RP/0/7/CPU0:R1(config-isis-if)#address-family ipv6

RP/0/7/CPU0:R1(config-isis-if-af)# exit

RP/0/7/CPU0:R1(config-isis-if)#exit

Notice I did not specify an IS-IS Level when I started, but we can set this

to Level-2

RP/0/7/CPU0:R1(config-isis)#is-type level-2-only

Now, when we show the config, you will notice Level-2 is set to the top of

the config when applied, not in the order I entered it. This is the beauty

of a staging config, you can enter some things in the wrong order but they

will be applied in the correct order.

RP/0/7/CPU0:R1(config-isis)#sh config
