I have two sites that are connected through a direct link from China Telecom. One site is in Sydney and the other is in Shanghai. I have a ProCurve 2900 switch at the Sydney end and a HP 1910 switch on the Shanghai end. Both of the sites also have Cisco ASA 5505's. The issue is that the Shanghai end can talk to Sydney but that the Sydney end can't talk to Shanghai. I think the issue is the IP routing on the Sydney end but I am not 100% about the rule. Both ends have VLAN's setup to support the each IP ranges.
Sydney has 4 VLAN's but I am only interested in VLAN 1 and VLAN20 (Shanghai). VLAN 1's IP range is 10.0.0.1 and VLAN20's IP range is 10.0.1.6. The gateway is 10.0.0.1
Shanghai has 2 VLAN's. VLAN 1 is 10.0.1.2 and VLAN 2 is 10.0.0.5. The gateway is 10.0.1.2.
I was thinking something like: 10.0.0.0 255.255.255.0 10.0.1.2 but that doesn't work. I know what I am doing wrong is simple but I can't find out where the issue is.
I have a network diagram and the config files that I can post if required.
