Multi Router and connection help please

I have router a , b , c conected to a switch remoted to another router going to the internet. Speed seems to come and go on the network would the switch be the cause of the slow downs all the router are running diffrent networks at /24 using 532a boards, and 2.9.38.

if everything s ok with switch and cabling there should not be a problem, connect to your routers and check bandwidth on interfaces.

Thanks, btw I am running ospf and I am showing full and 2way in the nieghbors I have more than one full, on different routers in the network. What does the full really mean or do for me? example router a and c would have both listed as full and the gateway also full? And should I have more than 1 full in the list? Some router have many full listed.

as it is written here:
http://www.mikrotik.com/testdocs/ros/2.9/routing/ospf_content.php#8.55.7

:arrow_right: 2-Way - the routers add each other to their Neighbour database and they become neighbours
:arrow_right: Full - the link-state databases are completely synchronized. The routers are routing traffic and continue sending each other hello packets to maintain the adjacency and the routing information

so if state is full, they exchange hello packets and exchange routes actively, in 2 way they see each other, but it is cheaper to get routes from somebody else, so they do not exchange their routed directly.

also, i might be wrong, would be good if someone could point out that i am wrong or confirm.
