Hi Nanog Members, I've been troubleshooting this problem for a few days already but i'm still unable to fix it. I think it's now time to ask some help from Nanog members. I cannot ping the IP on my Cisco 6509 from the internet. Here are the setup: *Internet*---(copper)-->*GSR*----(fiber)--->* Cisco 6509* <<<<<This setup is NOT OK - I cannot ping *Internet*---(copper)-->*GSR*----(copper)---> *Cisco 6509* <<<<< This setup is OK - I can ping(this is directly connected to the PRP2) NOTES: - I am using PRP2 on my GSR and the fiber is connected to the 4xGE module - I have a default route from Cisco 6509 to GSR - From the 6509 I can only ping the IP addresses on the GSR, addresses outside the GSR are not reachable - From the internet, I can only ping up to the GSR - I can ping from GSR to 6509 and vise versa - The IP on the 6509 is configured on the interface that is directly connected to the GSR. Thanks, -bong
