Hi,
running a traceroute a noticed this:
traceroute 10.191.21.1 source 10.191.11.1
Type escape sequence to abort.
Tracing the route to 10.191.21.1
1 10.191.111.14 24 msec
10.191.111.10 20 msec
10.191.111.14 8 msec
2 10.191.111.2 20 msec
10.191.111.6 16 msec
10.191.111.2 24 msec
3 10.191.121.5 12 msec 16 msec 16 msec
4 10.191.121.13 12 msec 24 msec *
is this nornal? I have attached a diagram for a better understanding of the route that the icmp packet goes from 10.191.11.1 to 10.191.21.1.
Thanks in advance.

it looks like you have equal cost multi pathing from 10.191.11.1 to 10.191.21.1 using both uplinks 10.191.111.14 and 10.191.111.10 not sure if you are using at that L3 switch to the routers HSRP,GLBP or routing
if its rouitng can you post the L3 siwtch of the rourse show ip route 10.191.21.1

Hey mate thanks for your repply...
I'm not using HSRP neither GLBP...
I am running EIGRP on the L3 switches (stacked) and BGP on the routers. I am also redistributing EIGRP to each other BGP.
Ithink I have found my problem. When redistributing BGP into EIGRP I reckon I created the loop shown above.
Thank you very much for your repply though.
Cheers,
Fabio
