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
Thu Mar 29 22:09:12.786 UTC
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.
