Router Line Clocking Source

[evildik]

I have a router that has a configuration of the following


O----1----2
/ \
/ \
/ \
/ \
3 4


Each number represents a router They are all connected with Point to Point Private T1's What should the clocking source be for each of these serial interfaces for router 1? and for routers 0,2,3,4

I have Router 1 each of the interfaces set for clock source internal and all the Routers 0,2,3,4 set for clock source line.

The problem im running into is the line keeps dropping and I am pretty sure its a clocking issue at this point

The default is for clock source line. With point to point you must designate one side of each as clock source internal.

That is what i thought so the core router which is router 1 should be clock source internal on all interfaces
and each outlying router should be clock source line?

Think that would work.
