Hello,
I have the ff setup: 2 cisco 2501s and two unmanaged
switches connected over a provider's ethernet VPN
network.
switchA ----------------------- switchB
| provider ethernet |
| network |
LAN A LAN B
Connected to switch A are 2501A and serverA. Connected
to switchB are 2501B and serverB.
ServerA and 2501A are part of LAN A ip address, say
10.1.1.0/255.
ServerB and 2501B are part of LAN B, say 10.1.2.0/255.
Provider will provide separate VLAN and /30 ip
address.
/30 will be assigned to ethernet ports of 2501s. I
will configure GRE tunnel between 2 2501s so that LAN
B and LAN A can see each other. will just put static
routes to the tunnel interface for these.Secondary ip
addresses on the 2501s will be configured for each
LAN.
This could be the config
router A
Tunnel 0
ip address 10.0.0.1 255.255.255.252
tunnel source 192.168.1.1 255.255.255.252
tunnel destination 192.168.1.2 255.255.255.252
!
Ethernet0
ip address 192.168.1.1 255.255.255.252
ip address 10.1.1.254 255.255.255.0 secondary
ip route 10.1.2.0 255.255.255.0 192.168.1.2
router B
Tunnel 0
ip address 10.0.0.2 255.255.255.252
tunnel source 192.168.1.2 255.255.255.252
tunnel destination 192.168.1.1
!
Ethernet 0
ip address 192.168.1.2 255.255.255.252
ip address 10.1.2.254 255.255.255.0 secondary
ip route 10.1.1.0 255.255.255.0 192.168.1.1
Is this solution possible??
