Sen,
1) Its good practice not to rely on arp to do the ip mapping work for you.
None of the prep-labs I have done so far use inverse-arp, so I assume this
must be something that is also done in the CCIE lab.
2) When running multicasting over frame-relay the preferred way is to use
sparse-mode along with the command "ip nbma-mode".The performance impact of
pseudobroadcast in pim-dm mode on frame-relay networks is what makes it a
poor choice . For more info see "Developing IP multicast Networks" page 454
Cheers,
Pierre-Alex

Subject: frame-inarp and nbma mode.
is it a good practise to disable inverse-arp in physical and sub-interfaces
while doing static mapping at subinterface-level, as all dlci's by default
maps to the physical interface & inverse-arp is on. i think disabling
inverse-arp at the sub-interface alone doesnt make a good sense as all pvcs
will still be active at the phsycial level.
and when running multicasting according to the cisco web you use nbma mode
on nbma(fr/atm) networks. but do you always use nbma-mode while running
sparse-mode. i set up a test network and my multicasting works either with
nbma mode on/off.
i'd take your help.
thanks, sen
