Glad this is helping! I also use SRX345's. They use the term 'routing-instance'. The 'virtual router' type is most similar to Cisco's VRF-Lite, as discussed in this video networkdirection.net/articles/routingandswitching/juniper-routers-and-switches/juniper-routing-instances/

Awesome video, once again! I also really enjoy how you run into errors on purpose, because that's likely what someone configuring VRFs for the first time would run into. But a little sad that it's only available on an enterprise service license level in IOS, if you run another license level on your L3 device, you won't be able to use VRFs. :(

how come adding the router will allow hosts from different VLANs to communicate with each other? (without additional config. like a router on a stick.)

On using the global routing table with VRF's? Sure. I like to use the global routing table for infrastructure. If I have a few routers, I will connect them and get BGP (or some routing protocol) working in the global routing table. Then a customer comes along. I don't want them knowing about all my routes. I just want to help them move packets around while keeping my infrastructure secure. That's when I would create a VRF. Customers will have their own routes, and they will all go in the VRF. Extra customers get their own VRF's too. As you get to part 3 of this series, this will probably make more sense.

he is pinging (ping vrf custB 10.20.0.1) unsuccessfully. How it could be successful; he did not define the route to 10.20.0.0 for custB vrf?

Thnxxxxxxxxxxx!!!!!

I've never heard of VRF's before. Is this new? What products support this feature? How do we know if a certain product supports this feature?

In part 2, I'll show you how to configure dynamic routing (OSPF and EIGRP) with VRF's, which might be similar to what you're asking for. I'm not sure how you would use RIP for active and OSPF for secondary though. For dual-ISP, I would use BGP

Amazing Explanation about VRF. Great work bro !!! How can the overlapping ip subnet 10.10.0.0/24 exchange between them ? what is the feature in the FW that can allow it ?

@NetworkDirection

5 жыл бұрын

The only way to have overlapping subnets communicate with each other is by sending the traffic to an L3 device (router or firewall), where there is no VRF, or the traffic is in the same VRF. This device then needs to use NAT to make the networks appear unique. It's a complicated scenario, so avoid it if you can
