Enabling Traffic Parameters on page 8 8 Routing Updates The way the router sends routing updates over a WAN SVC differs depending on the number of adjacent hosts per circuit If you have configured only one adjacent host per circuit Nortel Networks recommends that you set the routing mode to dial optimized so that the router sends routing updates only when data traffic causes the router to establish an SVC to the adjacent host When you have configured multiple adjacent hosts per circuit the router should send routing updates periodically to ensure that all hosts in the subnet have complete knowledge of the network topology In this case you should use the normal routing mode instead of dial optimized routing For more information about configuring routing updates see Changing the Routing Update Policy on page 8 5 PVC Operations and Management Concepts In most ATM networks if a PVC fails the remote device does not receive notification of the failure at the ATM layer Instead the device receives this information from a non ATM source such as a routing protocol that operates above the ATM layer The PVC Operations and Management OAM feature provides a mechanism by which ATM devices can receive prompt failure information 308612 14 00 Rev 00 1 41 Configuring ATM Services PVC OAM has two methods of detecting PVC failure loopback and alarms You can use either of these methods separately or both methods together W

ARP server a Router B ATMO0037A Figure 1 12 IP Logical IP Subnet 1 30 308612 14 00 Rev 00 Understanding ATM ATM Router Redundancy and OAM ATM Address Resolution An address resolution protocol defines a mechanism that enables an IP router to use the IP address of a network device to learn the physical address of that device An Ethernet LAN uses ARP as its address resolution scheme A LIS uses an address resolution scheme called ATMARP as defined by RFC 1577 On a LAN defined as a broadcast medium a router obtains the physical address of a network device by broadcasting an ARP request In a LIS which uses a nonbroadcast ATM medium a router sends an ATMARP request to an ATMARP server Each IP interface on the LIS opens a VC to the ATMARP server and registers its IP address and ATM address Figure 1 12 on page 1 30 Using this information the server builds and maintains a table that maps LIS IP addresses to ATM addresses A router that needs the ATM address of a host on the LIS sends an ATMARP request to the server When the server returns a response containing the address the router extracts the ATM address of the host from the response and opens an SVC directly to the host using ATM UNI signaling If the server does not have an entry for the requested IP address it returns a negative acknowledgment signifying that the destination is unreachable 308612 14 00 Rev
