Hello,
I'm planning to move all of the routing to our juniper EX2200-c switches. We have 2 that are connected together in virtual chassis mode in different buildings. Because of that, I cannot have 2 default route for 2 different vlans since it's considered as 1 switch now and has only 1 routing table (if I'm wrong about anything, please correct me). The goal was to have the people in 1 building going out on the internet with their firewall and the other people in the other builder going out on their firewall in their building. Both EX2000 are connected to other switches which have a fiber between them also. Now I read about virtual routers and I think that it's what I'm looking for to solve my default route problem. I use layer3 vlans. I plan to give my 2 virtual routers an ip address in the same subnet (ex 10.0.0.1 and 10.0.0.2) I would like them to be redundent so I was thinking about adding all of my vlan interfaces in each routing-instances (ex vlan.10,vlan.11). Here is a very simple diagram
Here are my questions:
- Will both VR will be able to ping each other since they are on the same subnet ?
- Will I have a problem since I want to add the same vlans to both to have redundancy ?
- Will they try to communicate using the vcp link or will they use the other link ? I would like to use the other link, not the vcp one, to pass the traffic between them.
- Can I use a vlan without adding it to a virtual router ?
- Can I have 2 virtual router on the same subnet ?
- Can I use the default routing table (inet.0) and the virtual router at the same time ?
Thanks for your help !
