This is driving me nuts. I'm sure the problem is starring me in the face but i need a little help.
I am working on a BSCI lab for multicasting but I have a routing problem.
Here is the setup.
R1 < - > R2 < - > SW1
R1 s1/0 connects to R2 s1/0 via serial.
R2 fa0/0 connects to a switch SW1 f1/1 via fastethernet.
SW1 has VLAN20 in its vlan database.
SW1 fa1/1 has switchport mode access, and switchport access vlan20 applied.
*SW1 has "ip default-gateway 172.16.20.2" applied
the serial link has IP of 172.16.102.0/29 with R1 on .1 and R2 on .2
The fastethernet link has an IP of 172.16.20.0/24 with R2 fa0/0 on .2
VLAN20 on SW1 has the ip of 172.16.20.4
EIGRP is setup on R1 and R2 with the following setup:
Router EIGRP 1
R1 can not ping 172.16.20.4
R1 has a route to 172.16.20.0/24 via R2's serial link.
my brain(and the lab i am working on) says this should work but it doesnt.
any help is greatly appreciated.
*crap, sorry had some incomplete information
I am thinking ip routing may be enabled in the switch, which would make ip default-gateway command irrelevant.
Can you post 'show ip route' from the switch.
