I don't think I need to add my "Inside" network to EIGRP! Do I?
Well YES I do want to use classless. But how can I confirm the versions that
support masks? I cannot find this info easily on CCO. Is there an easy way?
Do I need to contact someone at TAC for that?
Also I could NOT find any "good" examples of using EIGRP on GRE tunnels on
CCO.
Thanks for your help,
Tarek

Hi Tarek,
You should use a seperate Network for the Tunnel Interfaces.. and it can be
anything and the other side of teh tunnel should be a part of the same
network...
like this {----} tunnel interface on RouterA - 10.1.1.1 -------
10.1.1.2 - tunnel Interface on RouterB {---}
Additionally u should be able to make it passive if you want, but you should
add the Inside as well as the Tunnel Interfaces into EIGRP.. also if ur
using Classless addresses, do make sure to do "no auto" and you can use the
mask as in OSPF from 12.1 i think.. someone might wanna confirm that..!
Do a search on CCO also with GRE & EIGRP/OSPF, they have some nice samples
just come up...!
Regards,
Aamir

Subject: Quick question: GRE and EIGRP
If I'm running EIGRP on a router and I would like to apply it on a GRE
tunnel that happens to be using some Ethernet interface, can I make the
Ethernet interface passive because I do not want it to participate in EIGRP
updates?
int Tunnel63
ip add 192.168.20.5 255.255.255.0
tunnel source fa0/0
tunnel destination 192.168.20.2
tunnel key 63
int FastEthernet0/0
ip address 192.168.20.1 255.255.255.0
router eigrp 4
network 192.168.20.0
passive-interface fa0/0
no auto-summary
Well, can I use the same network number for the tunnel AND the underlying
physical interface to begin with?
Also for EIGRP, can I use a mask the way I do with OSPF? I heard that
starting with some IOS release I can. Please verify.
Thanks
Tarek
