two routers OSPF

RouterOS Forwarding Protocols
1

Hello there,

I am trying to connect 2 routers with OSPF. After everything I’ve read and followed many guides how to set up ospf I came to point where from router A (RB1100X2H) I can ping router B (RBSEXTANT), see him in neighbors list but I can access that router only via MAC telnet and router B doesn’t show in winbox. After setting up the configuration I’ve tried to connect router B directly to my computer and again with no success. I’ve reconfigured them like 10 times following different tutorials but again nothing. What should I provide to you so I can get some help?

Thank you in advance

The configs (output from /export compact) and a simple diagram of what is connected where would be a good starting point.

and router B doesn’t show in winbox

I assume you are referring to winbox neighbor discovery. Winbox discovers routers in the same L2 broadcast network.

Simple diagram of what I've done till now is attached to this message. CelticComms here is what you've been looking for:

anyone here to help?

I’ll take a look at the config, but here are the most common OSPF neighbor issues:

Duplicate router ID
OSPF Network type mismatch
MTU Mismatch
Multicast for ospf (224.0.0.5 and 224.0.0.6) not permitted
Network subnets advertised don’t match on either side of the adjacency
Mismatched hello/dead timers

Cisco has a great doc on OSPF troubleshooting that is valid for all platforms since OSPF is open standard

http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094050.shtml

Check your router ID’s in
/routing ospf instanceBecause I do not see them in your config, I assume they are default, and therfore all routers will have 0.0.0.0.
Set them differently on all 4 (like you did with the loopback IP’s which you probably created for the router ID’s)

8

Change your IP addresses to a Class A, B or C range - I did a quick test of this on two MikroTik VMs and could not establish a neighbor adjacency - as soon as I switched to RFC 1918 space (192.168.0.0/30) the neighbors immediately came up.

The IP addresses you are using are in the Class E - Experimental range which is not supported by all network devices in the TCP/IP stack

See this article for more info:

http://packetlife.net/blog/2010/oct/14/ipv4-exhaustion-what-about-class-e-addresses/

Another interesting note on this…I attempted to put the same address into a Cisco router and it won’t even accept it on the interface:

R2(config-if)#ip address 253.25.0.5 255.255.255.252
Not a valid host address - 253.25.0.5
R2(config-if)#
