Configuring IS-IS over a GRE IP tunnel
Brocade IS-IS Router B configuration
To configure Brocade IS-IS Router B for the IS-IS Point-to-Point feature use the following commands.
Brocade(config)# interface ethernet 1/1
Brocade(config-if-e10000-1/1)# ip router isis
Brocade(config-if-e10000-1/1)# ip address 10.10.2.2
Brocade(config-if-e10000-1/1)# isis point-to-point
Brocade C configuration
To configure the Brocade C router for the IS-IS over a GRE IP tunnel feature, use the following
commands.
Brocade(config)# router isis
Brocade(config-isis-router)# exit
Brocade(config)# interface tunnel 1
Brocade(config-tnif-1)tunnel source 10.0.8.108
Brocade(config-tnif-1)tunnel destination 10.108.5.2
Brocade(config-tnif-1)tunnel mode gre ip
Brocade(config-tnif-1)isis point-to-point
Brocade(config-tnif-1)ip address 10.10.3.1/24
Brocade(config-tnif-1)exit
Brocade(config) ip route 10.10.2.0/24 10.10.3.1
Brocade D configuration
To configure the Brocade D router for the S-IS over a GRE IP tunnel feature, use the following
commands.
Brocade(config)# router isis
Brocade(config-isis-router)# exit
Brocade(config)# interface tunnel 1
Brocade(config-tnif-1) tunnel source ethernet 5/1
Brocade(config-tnif-1) tunnel destination 10.0.8.108
Brocade(config-tnif-1) tunnel mode gre ip
Brocade(config-tnif-1) isis point-to-point
Brocade(config-tnif-1) ip address 10.10.3.2/24
Brocade(config-tnif-1) exit
Brocade(config) ip route 10.10.1.0/24 10.10.3.1
Displaying IS-IS over GRE IP tunnel
You can use the show isis interface command to determine if IS-IS point-to-point is configured on a
tunnel interface. In the example below, the lines in bold identify IS-IS point-to-point configuration in
the gre_tnl 1 interface.
