Option 2 – Partial OSPF network:
•
Configure the Planet Operate server with static routes to reach the Cyan nodes.
•
Enable OSPF on the router on the LAN that it is sharing with the Cyan gateway node.
•
Enable OSPF on both of the Cyan gateway nodes.
6.4 Network and Host Routes
The Z77 Broadband Operating System Supervisor (BOSS) shelf controller card supports up to 258 network
routes and up to 258 host routes. In a network with a large number of IP/OSPF routes, exceeding either or
both of the network routes and host routes supported by the BOSS card can cause other processes, such as
service provisioning, to be delayed in varying degrees in its execution.
Additionally, a Z77 node might lose its connectivity and report a COMM Fail alarm when participating in a
large network with several network routes and host routes that exceeds the limit supported by a Z77 BOSS
shelf controller card.
If you are using proxy ARP or static routing, you will not be affected unless you have 258 or more Cyan
nodes in a single network.
Note:
Shelf management cards for non-Z77 Cyan shelves – including the Z22, Z33 and L-AMP shelves –
provide up to 700 network and host routes combined for each shelf. Exceeding the upper routes limit in a
non-Z77 shelf can cause other processes, such as service provisioning, to be delayed in varying degrees in
its execution.
For large networks with a significant number of IP/OSPF routes, limiting the number of routes injected into
the Cyan network will avoid excessive network routes and host routes.
