We’re trying to install a new design for our edge environment using vxlan between two datacenters. For the most part it all works, but we are having an issue with a route advertisement we had working with a former technology using null routes. The null routes however in an arista environment seem to break routing completely.
Attempting to install both a /24 and a /23 route in each of two datacenters:
Primary path for 10.10.0.0/24 and also advertises 10.10.0.0/23 (for backup path to 10.10.1.0/24)
Primary path for 10.10.1.0/24 and also advertises 10.10.0.0/23 (for backup path to 10.10.0.0/24)
Have attempted to place both 10.10.1.0/24 and 10.10.0.0/23 in the BGP config as network statements using the bgp advertise-inactive command, but it only advertises the 10.10.0.0/23 address as I do not have a connected route in the /24 address space.
int vlan 101
ip address 10.10.1.0/23 is installed (because the interface is on a /23 vxlan in both datacenters)
How can we force a route to be advertised via BGP if it doesn’t exist (used a null route in the past to accomplish this)
