I can ping all routes save two in my topology. The two routes I can't ping are in the routing tables of the spoke routers, but pings from spoke to spoke get black-holed at the hub frame router.
I know this is a frequently-encountered problem, and I thought I could solve it by disabling ip split, but nothing I do works.
Can one of you help?
Briefly, I have R3 as the hub and R1 and R5 as spokes. I am using PPP over FR using virtual templates. The adjacencies all form and I can ping all routes except 150.1.1.1 and 150.1.5.5
Here's my config:
