On erx1, create two IPSec tunnels, one to carry customer A's traffic and another to
3.
carry customer B's traffic. You must create each pair of tunnels in the virtual routers
where the IP interfaces reaching those customers are defined. Create the endpoints
for the tunnels in the ISP default virtual router.
Virtual router A:
erx1(config)#virtual-router vrA
erx1:vrA(config)#
Tunnel from Ottawa to Boston on virtual router A:
erx1:vrA(config)#interface tunnel ipsec:Aottawa2boston transport-virtual-router
default
erx1:vrA(config-if)#tunnel transform-set customerAprotection
erx1:vrA(config-if)#tunnel local-identity subnet 10.1.0.0 255.255.0.0
erx1:vrA(config-if)#tunnel peer-identity subnet 10.3.0.0 255.255.0.0
