I am having trouble pinging bgp routes that seem to be OK.
r5 --- r7 --- r8
bgp bgp
Below are 2 pings of bgp routes and an OK ping of loopback
r5#p 193.168.10.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 193.168.10.1, timeout is 2 seconds:
U.U.U
Success rate is 0 percent (0/5)
r5#p 193.168.11.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 193.168.11.1, timeout is 2 seconds:
U.U.U
Success rate is 0 percent (0/5)
r5#p 150.50.8.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 150.50.8.8, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 36/36/36 ms
r5#
Below are show routes and bgp routes and neighbors followed by the
config for r5 and then the config for r8.
r5#i
