11.14.2.4 Routing Tables

Each domain has its own routing table. Each routing table contains entries that, based on the

destination IP address, control where the MSC forwards packets (for upstream and

downstream traffic). The MSC automatically creates routing table entries for each downlink

interface and for each edge router in the domain. You can create additional entries by

specifying the edge router to which the MSC should forward traffic for a particular destination

IP address or IP subnet.

11.14.2.5 PVCs

IP bridge PVCs are similar to regular PVCs and are endpoints of the IP bridge. In addition, IP

bridge PVCs are one of two types, IP over Ethernet or IP over ATM, depending on the

underlying network.

The PVID is used to identify the domain the PVC is in, so the PVID must be in a domain.

11.14.2.6 ARP Proxy Settings

The MSC is an ARP proxy for edge routers and subscribers in an IP bridge. You can configure

basic settings for this, and you can look at (and flush, in some cases) the (PVC, MAC, IP, VID)

information the MSC has learned using DHCP snooping and ARP.

11.14.3 IP Bridge Configuration

Follow these steps to set up a simple IP bridge.

1 Create a domain. (Each domain is an ISP.)

2 Create one or more VLANs in the domain. (For example, one VLAN is for high-speed

Internet, and another VLAN is for VoIP.)

3 Create the VLAN in the system using the regular screens or commands for VLANs.

4 Specify one or more edge routers for the domain.

5 Create routing table entries, so the MSC forwards frames to the appropriate edge router.

6 Create downlink interfaces, so the MSC forwards frames to the appropriate subscribers.

7 Create PVCs for the subscribers.

Use this screen to configure how long the MSC keeps entries in the ARP table. You can also

flush the Address Resolution Protocol (ARP) table for each domain.
