I'm looking for any type of help please, I'm starting to go around and round and finding myself looking to get more aggressive with config changes which I'm sure will push me in a bad direction.
I'm having issues with the 'Over_NET' DMVPN, its a DMVPN tunnel that I need to push through another DMVPN.
This is also over 2 diverse WAN Paths (1&2).
The WAN paths and Tunnels (2&3 - Under_NET) are good.
The new setup to support new locations has same WAN Paths but 2 new Tunnels (7&8 - Under_NET) they are good.
I'm tryin to add another tunnel in Under_Net called Over_NET (4)
I can see Tu4 is:
UP/UP on Hub
UP/DOWN on Spoke.
SPOKE: Tu4 is missing from 'sh ip nhrp multicast', but exists in 'sh ip nhrp details'.
HUB: Tu4 is missing from 'sh ip nhrp multicast', & 'sh ip nhrp details'.
This makes me think its a multicast issues, but I've gone over and over the routers to make sure PIM is across interfaces and enabled.
Over_NET is tied to Under_NET Lookbacks.
Tring to keep all in Uder_NET and global, within the HUB RT.
The other area that could be effecting this is the EIGRP setup witch I have little experience with.
Any suggestions and ideas of this to test please advise. I'm at the end of my limits. TY
