NimbostratusBGP Over 2 vlans to 2 Network switch
Hi, im testing a new design for ltm, when’re big ip will have 2 transit vlans to switch a and switch b and then i ll establish bgp over it. Switch will advertise default to Big ip and big ip will ad...
Why 2 transit vlans?
Is't is more simple to advertise the Virtual Server subnet with the next hop being the Floating Self-IP in 1 transit vlan? During a failover or switch failure there is no routing recalculation, only L2 arp.
In Zebos you can create a static for the SNAT pool addresses to be send to Null. This will inject them in the BGP route table without the need to create a useless Virtual server.
Some BGP config snippets:
ip route 10.10.10.104/29 Null (for SNAT pool addresses)
route-map NEXTHOP permit 10
set ip next-hop 10.10.105.195 primary (this is your floating self IP in the transit vlan)
