Hi All,
Thanks a ton for the help on the Frame Relay queries, & I seem to be much
more comfortable now. Just a few more queries in response to the answers
I have recieved.
1. While using a Frame Relay point to multipoint configuration, Will the
following configuration be okay for a Central site called "Site A"
connecting two remote sites Site B, & Site, which have connections only to
the central office, & not to each other.
Site A.
interface Loopback0
ip address 200.200.10.1 255.255.255.0
interface serial 0
encapsulation frame-relay
no ip address
interface Serial0.101 multipoint
ip address 128.213.10.1 255.255.252.0
ip ospf network point-to-multipoint
router ospf 10
network 128.213.0.0 0.0.255.255 area 0
Question: Can site A have two PVC's associated with the interface Serial 0
for connecting to the remote sites.
Site B
interface Loopback0
ip address 200.200.10.2 255.255.255.0
interface serial 0
encapsulation frame-relay
no ip address
interface Serial0.101 multipoint
ip address 128.213.10.3 255.255.255.0
ip ospf network point-to-multipoint
router ospf 10
network 128.213.0.0 0.0.255.255 area 0
Site C
interface Loopback0
ip address 200.200.10.3 255.255.255.0
interface serial 0
encapsulation frame-relay
no ip address
interface Serial0.101 multipoint
ip address 128.213.10.4 255.255.255.0
ip ospf network point-to-multipoint
router ospf 10
network 128.213.0.0 0.0.255.255 area 0
Will this configuration work, My doubt is that assume if a single
interface can be associated with multiple DLCI's, for two destinations as
assumed above,will OSPF routing works as expected. Or else do I need a
second interface to be explicetedly configured with a PVC assigned to it &
use it for connecting the second location. This would remove the idea
behind using multipoint configurations.
My understanding on the difference between point-multipoint & broadcast
configurations is that point-multipoint interfaces are a collection of
point-point links & broadcast configs emulate a broadcast domain. Correct
me pls.
Thanks in advance
Vinod.
