Routing Information Protocol

RIP is an interior gateway protocol, which means that it performs routing within

a single autonomous system. It is widely used to route traffic in the global

Internet.

RIP routers maintain only the best route (the route with the lowest metric value)

to a destination. After updating its routing table, the router immediately begins

transmitting routing updates to inform other network routers of the change. These

updates aresent independently of the regularly scheduledupdates that RIP routers

send.

Static Route Provisioning

The ONS 15454 SDH uses CTC to provision static network routes. Static routes

allow workstations to connect to ONS 15454 SDHs through routers. Static routes

also make it possible to have multiple CTC sessions with different destination IP

addresses on a network of ONS 15454 SDHs that are all on the same subnet. For

example, a NOC can remotely monitor an ONS 15454 SDH through CTC while

an onsite employee is logged into a network ONS 15454 SDH through a separate

CTC session. If OSPF is connected and running, static routes are unnecessary.

DCC Tunneling

You can tunnel third-party SDH equipment DCCs across ONS 15454 SDH networks.

A DCC tunnel is a series of connection points that map a third-party equipment DCC

to ONS 15454 SDH DCCs. A DCC tunnel endpoint is deﬁned by the slot, port, and

DCC type. To create a DCC tunnel, connect the tunnel endpoints from one ONS

15454 SDH optical port to another. DCC trafﬁc is forwarded transparently,

byte-for-byte, across the ONS 15454 SDH network.
