Hello all, i'm working on a lab scenario where R2 is the hub with a
multipoint f/r subinterface. R4 and R6 are the spokes and are using
the physical interface. R4 and R6 should from an adjacency with R2,
but R2 is getting an encapsulation failure when sending the hello
packets on interface s0.246. Here's the configs and relevant debug
output:

R4 and R6 do not see R2 as a neighbor at all, while R2 sees both R4
and R6 but shows them both in an Init state. Can anyone point out
what might be going on here?
TIA,
Matt
