But if you’re using private IP space, why limit yourself to /29s everywhere? Particularly if each site would have a site number, you could easily do: Site 33: 10.100.33.0/24<http://10.100.33.0/24> (.1 local radio, .2 local router, .101 remote radio, .102 remote router) Site 34: 10.100.34.0/24<http://10.100.34.0/24> (.1 local radio, .2 local router, .101 remote radio, .102 remote router) And so on… Leave yourself plenty of room and route bigger subnets. The site numbering idea might end up a little confusing, though, since “Site 33” is really TWO physical sites, and “Site 34” in my example above is TWO physical sites, one of which you’ve already called part of Site 33.
