We have a network block of 10.201.0.0/16 which is divided into two subnet 10.201.0.0/18 and 10.201.192.0/18. We are getting a internet feed for each subnet.
10.201.192.0/18 is in global routing table, and 10.201.0.0/18 is in a vrf-lite green.
I am thinking doing the following:
Hub and spoke are from perspective of vrf green.
For vrf green in the HUB:
ip route vrf green 10.201.0.0 255.255 255.192 vlan 199
ip route vrf green 10.201.64.0 255.255.255.192 vlan198
ip route 0.0.0.0 0.0.0.0 vlan199
ip route 0.0.0.0 0.0.0.0 vlan198
Suppose we already get the 2 internet feeds to HUB route with vrf green and global routing table. This should get vrf green going.
But we also have global routing table on the HUB router.
We would like to have 10.201.0.0/16 communicating with each other, and only keep internet default separated.
How should we get to 10.201.0.0/18 from global routing table and how should we get to 10.201.192.0/18 from SPOKE?
