Yes, and that is why the route shoudn''t be there, correct?

route)
Halabi (and the spec) says that the next hop does not have to be
directly connected to the router but a route to the next hop does have
to be in the IGP. Your next hop is listed as 137.20.20.1, which is not
in your route table as a connected or IGP route. Try throwing a static
in to the 137.20.20.1 address or having an IGP advertise it. I don't
believe the recursive lookup reference a default route.
Configs would be helpful as well :)

Please take a look at the following "sho ip bgp" and "sho ip
route" and tell me what is wrong with this picture, and why this is
happening? According to page 149 of Halabi's book, this shouldn't be.
(Hint: R1 can't ping 137.20.20.1)
