We continue the previous multicast lab. This time we take a look at how RPF check works, how we can prevent RPF failures, and how we can fix RPF issues with static mroutes. PIM uses RPF checks to prevent multicast routing loops. If a router…

These features allow us copy the traffic of a switchport or an entire VLAN and send the copied frames to another switchport. This destination port (where we send the copied frames to) can be on the same switch (SPAN), on a different switch in the…

In the previous post about VPLS implementation we configured the remote PEs manually under the VFI, like this: This solution is not scalable if the customer has a lot of remote sites and we have to configure each PE router manually, since we need a…

We're going to configure Layer 2 services for customers over an MPLS cloud using SR OS routers. First we're going to take a look at the P2P service called Epipe which effectively turns the MPLS cloud into an "emulated wire" and connects the two customer…

I've been experimenting with different router images and I tried to establish the OSPF neighbor adjacency between a Cisco and an Alcatel (SR OS) router. OSPF is an industry standard routing protocol (unlike ISIS for example), so it should be supported on both platforms and…
