IDRP doesn't use GDP, just ICMP. GDP was a Cisco proprietary protocol that preceded IDRP, and Cisco deprecated it -- I didn't think it was even supported any longer. The main operational problem with IDRP is, given its default timer settings, discovery is very slow. Alternatives in the UNIX world including using RIP for router discovery. IPv6 has neighbor discovery mechanisms that will meet this need. It's probably faster all around to have hosts get a default router address through DHCP, and have this address be a HSRP virtual address when there are multiple routers. > >Thinking about it this morning though, I have never tried advertisements >from different interfaces to a router.
