IP Routing

I have VIRL installed on my HP Microserver running ESX, but having a few problems with running the simulations. :( I can't seem to telnet to the console port when the simulation is running. But that's a problem for another post and day. I really needed to do some solid lab work so went back to INE labs for a bit.

Today I reviewed static IP routing and the differences between setting next-hop, exit interface or both.

A few points I learnt are:
  • in DMVPN the hub can not use only exit-interface, it must use next-hop;
  • static routes using exit interface on a multipoint interface can have ARP issues;
I also reviewed the use of SLAs in creating redundancy in the routing table.
