Trace route question

[nguyenvinnie]

I do not understand what's happening at hop 1 and 4 on the trace results below, looks like the packet is bouncing between the two interfaces, can someone explain?

TIA

Type escape sequence to abort.

Hop 4 is load-balancing the packet but neither interface is able to reach hop 5

-or-

hop 5 isn't allowing the traceroute packet /or/ you have an ACL in your router against hop 5 and the rest.

I would guess is the latter since cisco.com is up 🙂

OK, that answered my question.

Now I know the packet was bouncing between the two interfaces because of load balancing. I forgot to mentioned that hop 5 is PIX.

Thanks for your help.
