Routing Protocol Configuration; Proxy Arp - Nortel Optical Multiservice Edge 6130 Planning Manual

IP address configured and is in the same level 1 area. iISIS routing protocol
also creates CLNP forward information base (FIB) updates based on LSP
database for all reachable OSI network elements.
iISIS routing implementation rules
You must observe the following rules when you implement the iISIS routing:
• Support provisioning of three manual area addresses:
— MAA1 default value of 490000
— MAA2, blank with 3 to 13 bytes long
— MAA3, blank with 3 to 13 bytes long
• Level 1 routing is supported
• Enabling and disabling of iISIS routing protocol is done on a per PPP,
LAPD based DCN interface. The default value is iISIS-Disabled.
• The iISIS routing protocol will support only configuration of default
metric as the routing metric for each circuit. The range of the default metric
shall be [1 - 63] and the default value is 4.
• Route redistribution between OSPF and iISIS routing protocols is not
supported.

Routing protocol configuration

OME6130 supports nodal level configuration of enabling or disabling of
Integrated Intermediate System Intermediate System (iISIS) routing protocol.
By default, iISIS routing protocol is disabled. OSPF routing protocol is always
enabled at the nodal level, but must be provisioned per network interface.
OME6130 supports enabling of iISIS at a nodal level, while OSPF is also
enabled on the NE. The routing protocols must be specified for each network
interface individually. iISIS and OSPF routing can not be simultaneously
provisioned on the same network interface.

Proxy ARP

Proxy ARP allows a gateway network element to respond to address resolution
protocol (ARP) requests for subtending network elements that are within the
same subnet as the customer DCN address range. The proxy ARP feature
removes the need for customers to provision static routes on their routers and
routing protocols (OSPF) between the gateway network elements and the
customer DCN.
Proxy ARP is only supported on the LAN interface of the OME6130 network
element. At the gateway OME6130 network element, the IP address of
neighbouring network elements can be provisioned for Proxy ARP. The GNE
will perform proxy ARP for IP addresses of neighbouring NEs that are on the
same subnet s the DCN router connected to the LAN interface.
