support representative for more assistance.
2.
Crossed serial circuits with
multiple lines between two
routers
1.
Check the physical attachment of serial lines to
ensure that they are correctly wired.
2.
If necessary, rewire the lines and check the
output of the

and
show appletalk interface
commands to
confirm that the interface and line protocol are
up.
3.
If the router still cannot find routes, consult your
technical support representative for more
assistance.
Software problem
If the router issues a message that says “restart port
pending,” upgrade to the latest system software
maintenance release or contact your technical
support representative.
