Psuedo-Distributed Virtual Routers with Vyatta VM

I’ve got a stretched VLAN design using OTV and HSRP isolation/localisation I’m doing at work and was thinking how you would simulate FHRP isolation or something like it using a Vyatta VM. Unlike VMware’s NSX virtual router, the Vyatta router is not distributed. It can only be on one host at any point in time […]

It’s only “routed” in that it represents a way out of the org. network. NAT isn’t ideal when dealing with things like VoIP and I’m thinking of a use case where a […]
