Configuring IP Interfaces for PoS Links
Configuring IP interfaces for PoS links is generally the same as for WANs and for LANs.
You assign an IP address to each interface and define routing mechanisms such as OSPF
or RIP as with any IP network. You can configure the IP interface on the physical port or
you can configure the interface as part of a VLAN for PoS links. You can also configure
multiple IP addresses for each interface, as described in “Configuring IP Interfaces and
Parameters” on page 78.
When creating the IP interface for a PoS link, you can either specify the peer address if it is
known (static address), or allow the peer address to be automatically discovered via IPCP
negotiation (dynamic address). If the peer address is specified, any address supplied by the
peer during IPCP negotiation is ignored.
IP interfaces for PoS links can have primary and secondary IP addresses. The primary
addresses may be either dynamic or static, but the secondary address must be static. This
is because only the primary addresses of both the local and peer devices are exchanged
during IP Control Protocol (IPCP) negotiation.
Source filtering and ACLs can be applied to an IP interface for a PoS link. Unlike WAN
ports, the applied filter or ACL presents no limitation. Different filters can be configured
on different PoS ports.
Configuring Packet-over-SONET Links
To configure a packet-over-SONET link:
1. On the SSR, assign an interface to the PoS port to which you will connect via fiber
cable in a point-to-point link. Assign an IP address and netmask to the interface. If
possible, determine the peer address of the interface at the other end of the point-to-
point link. In the following example, the port so.13.1 on the SSR will be associated
with the interface pos11:
Router A Router B
pos11
so.13.1
20.11.11.20/24
pos21
20.11.11.21/24
