Careful with IP Routes on Same Network.

[cjinsocal581]

Here is the setup:

2 sites. SCN setup between the sites.

Site 1 network: 10.10.0.1
Site 2 network: 10.20.0.1

Site 1 has an IP406v2 with two DS30's
Site 2 has an IP406v2 with one DS30

SCN was setup. VoIP works perfectly between the sites.

NOW, here is the problem that was noticed.

IF you add an IP Route in site 2 of 10.10.0.0, the DS30 at site 2 stopped responding. Once the IP route was deleted, it started working again.

I don't know if this has been mentioned or not here so I thought I would share the info.

Thanks, nice to know. Could you figure out why this occured. Also, what software level are you running?

 

[cjinsocal581]

Site 1 has 3.0.44
Site 2 has 3.1.29

The loads don't appear to have anything to do with it it looks like it has to do with the inner working of the networking modules for the IP Office itself.

I think the system got confused once I added the IP Route.

There was no VPN or anything setup between the sites either. This was a Direct T1 connection via two Cisco routers. The two sites were just on different subnets.

Funny thing is, I added IP routes at a different site over a VPN and this problem did not occur.

How did SCN work without an IP route between the networks ?

are they on the same subnet ?

and what masks did you have on all the routes

 

[cjinsocal581]

Site A network is: 10.10.0.1
Site B network is: 10.20.0.1

Subnet of 255.255.0.0

Did you enable ProxyARP on the IP Route? Thats the only thing i can think of in IP Office wich will gives the problem as described.
Unless the problem is in the network, you say SCN and VoIP works? Seems impossible without IP Routes so there must be some device taking care of the routing.
