Hi All,
I am facing a packet loss issue for few public ip's of around 40-60%.
I have force 10 core router for eBGP peering and below which lies my cisco catalyst C6509-NEB-A.
A TenGigabitEthernet connets the two port. Two subinterfaces. I will paste the config below.
Traceroute shows some strange packet drops between catalyst and Force10.
The bunch of intermittent IP's and working ip's are learning the same route via E-300 via IBGP.
Following are different running configs and routes learned collected from Catalyst:
TenGigabitEthernet2/2 unassigned YES NVRAM up up
TenGigabitEthernet2/2.2007 2tow_E3008 YES NVRAM up up
TenGigabitEthernet2/2.2012 unassigned YES unset up up
TenGigabitEthernet2/2.2024 10.16.0.113 YES NVRAM up up
TenGigabitEthernet2/2 is up, line protocol is up (connected)

where 198.173.3.56 is the pingable ip and 207.86.215.17 is the troubled one.
Please let me know what else is required.
