A lot of times we want to login to side “B” when the link between A and B is down…but we can’t unless each side is advertised as a /30..but I want the two radio’s to see each other when they’re up.
So what I’ve done most recently is: .1 = Router A (configured as /30) .2 = Radio A (configured as /29, GW set to .1) .5 = Radio B (configured as /29 GW set to .6) .6 = Router B (configured as /30) Then I just run OSPF on a separate /30 across that path on a separate VLAN. The above is just for MGMT of the radios. > On Aug 11, 2016, at 3:02 PM, Christopher Gray <cg...@graytechsoftware.com> > wrote: > > How do you setup radio addresses so both ends of a link can be accessed (via > loop) when the link is down? > > What I've been doing... and how it doesn't work: > I've been setting up OSPF links using a /29. > > Router A -- Radio A ~~ Radio B -- Router B > > Devices get addresses: > .1 - Router A > .2 - Router B > .3 - Radio A (Gateway set to .1) > .4 - Radio B (Gateway set to .2) > .5 - Spare (used when swapping links) > .6 - Spare (used when swapping links) > This feels very clean, and works nicely when the link is up or when there is > no network loop.
