Supporting next level IXP topologies

Netlab 1.4 sneak preview (unofficial)

Output of ‘fdp’ layout for ‘netlab create -o graph’

Imagine you are an IXP deploying technologies like RFC9161 EVPN with proxy ARP and MPLS over RSVP-TE, and you need to come up with a validated multi-vendor design. How would you go about that?

The Netlab team has got you covered. Check out this example — a sneak preview with upcoming Netlab 1.4 features (work in progress)

• S1/S2 are data center routers doing EVPN/VXLAN with proxy ARP; iBGP control plane and ISIS IGP. Anycast gateways are available in the ‘red-hot’ vlan
• C1/C2 are core nodes doing SRv6 over ISIS (one might call this BGP-Free :)
• PE1/PE2 are MPLS core nodes doing MPLS EVPN over LDP, with OSPF

…is all it takes to bring this topology to life!
