9.5.2 Configuration example
Objective:
Organize interaction between hosts terminated in two VRF vrf_1 and vrf_2.
Initial configuration:
hostname esr
ip vrf vrf_1
exit
ip vrf vrf_2
exit
interface gigabitethernet 1/0/1
ip vrf forwarding vrf_1
ip firewall disable
ip address 10.0.0.1/24
exit
interface gigabitethernet 1/0/2
ip vrf forwarding vrf_2
ip firewall disable
ip address 10.0.1.1/24
exit
Solution:
Create LT tunnels for each VRF, specifying IP address from one subnet:
esr(config)# tunnel lt 1
esr(config-lt)# ip vrf forwarding vrf_1
esr(config-lt)# ip firewall disable
esr(config-lt)# ip address 192.168.0.1/30
esr(config-lt)# exit
esr(config)# tunnel lt 2
esr(config-lt)# ip vrf forwarding vrf_2
esr(config-lt)# ip firewall disable
esr(config-lt)# ip address 192.168.0.2/30
esr(config-lt)# exit
Designate LT tunnel from VRF, which is necessary to establish link with, for each LT tunnel and activate them.
esr(config)# tunnel lt 1
esr(config-lt)# peer lt 2
esr(config-lt)# enable
esr(config-lt)# exit
esr(config)# tunnel lt 2
esr(config-lt)# peer lt 1
esr(config-lt)# enable
esr(config-lt)# exit
