[c-nsp] Quick routing question.

[Drew Weaver]

Howdy,

I currently have two connections to Level3 because I am upgrading, one (the old one) is a 1Gbps connection in Router-1, the second one is a 10Gbps connection in Router-2.

Both connections are up/up, the old connection is getting a full BGP session from Level3.

I noticed that no matter what I do, I can't seem to ping Level3's side of our 10Gbps interface on the new connection from either of the 2 routers

rtr#ping ip
Target IP address: x.x.x.13
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y
Source address or interface: x.x.x.14
Type of service [0]:
Set DF bit in IP header? [no]:
Validate reply data? [no]:
Data pattern [0xABCD]:
Loose, Strict, Record, Timestamp, Verbose[none]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to x.x.x.13, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
 
I am able to ping their side of the interface from hosts downstream from the routers, just not the routers themselves.

[root at vmz ~]# ping x.x.x.13
PING x.x.x.13 (x.x.x.13) 56(84) bytes of data.
64 bytes from x.x.x.13: icmp_seq=1 ttl=60 time=3.27 ms
64 bytes from x.x.x.13: icmp_seq=2 ttl=60 time=14.9 ms
64 bytes from x.x.x.13: icmp_seq=3 ttl=60 time=3.01 ms
64 bytes from x.x.x.13: icmp_seq=4 ttl=60 time=3.19 ms
64 bytes from x.x.x.13: icmp_seq=5 ttl=60 time=3.10 ms

I can't really think of any reason why I wouldn't be able to ping their end of the Interface from this router, connectivity is obviously good considering I can ping it from a host downstream from the router.

Is anyone aware of any sort of gotcha when doing something like this?
