Optical Multiservice Edge 6130
OSPF
— Configurable default area of 0.0.0.1
— Maximum of 150 routers in the same OSPF area as the OME6130 NE
— Supports non-stub area
— Configurable parameters:
– Hello Interval: 10 seconds. The range is [1-65535] seconds.
– Dead Interval: 40 seconds. The range is [1-65535] seconds.
— Non-configurable default parameters:
– Retransmit Interval: 5 seconds
– Transmit Delay: 1 second
– OSPF Ethernet Cost: 1
– OSPF DCC Cost: 1
– OSPF GRE Costs: 1
– OSPF LAN priority: 1
— OSPF Authentication mode : disabled (default) or Simple Password:
– Enabling and disabling of password based authentication for OSPF
on a per layer 2 interface level. If password based authentication is
enabled, then password is configurable.
— OSPF Authentication key: String configurable by the user if the OSPF
Authentication mode is set to Simple Password.
Note: For maximum network performance, the external DCN intervals
should be aligned with OME6130.
IP
— Maximum of 4096 IP routes (static and dynamic). But for optimal
performance it is recommended that not more than 512 entries be
added in the IP routing table. (Note that the IP routing table entries
include the routing entries added by OSPF or iISIS or Static Route into
the IP routing protocol domain).
— Maximum of 10 static routes per NE
– Use Destination Network IP address of 0.0.0.0/0 with next hop IP
address for default route
— MTU packet size of 240 to 512 bytes for OSI CLNP/LAPD
— MTU packet size of 1518 bytes for IP/PPP
GRE
— Tunnels between different OSI areas are supported
