Why does it bounce between .226 and .228? Routing issue?
Thx

There is a routing loop - i.e. router 2.x.184.226 knows the route to the destination via next-hop 2.x.184.228, whereas router 2.x.184.228 knows it via 2.x.184.226. The packet will 'bounce' between the 2 hosts until the TTL expires.

In simple speak Router .226 forwards it to router .228 but router .228 says 'have the packet back, you are the next-hop for that destination' and so on until they get bored and drop the packet (TTL expires)...
