ATM multipoint connection to ATM point-to-point

We are planning to lose connectivity through the one PVC after we reconfigure the local site connection with a point-to-point. We want to leave the hub router configured as a multipoint connection. Will this work? We plan to do this using these commands:

no interface ATMx/IMA0.1 multipoint

*reload router*

interface ATMx/IMA0.1 point-to-point

description ~text

bandwidth ~value

ip address x.x.x.x

ip pim sparse-mode

pvc 1/100

vbr-nrt ~xxxx yyyy 250

oam-pvc manage 15

oam retry 15 15 1

2. After we change the hub side as a point-to-point connection, is it ok to leave the local site pvc's configured as point-to-point and one as a multipoint connection for a couple weeks? Will it have any detrimental affect on multicast or unicast traffic?

Re: ATM multipoint connection to ATM point-to-point

As long as the PVC to IP mappings on the other end are maintained, you should be fine. If you are running OSPF on this link, you need to put ip ospf network point-to-point on the multipoint side so the adjacency will form.
