Re: OSPF: No ping to backbone [SOLVED]

Anyway, it seems that turning static redistribution off doesn't solve my problem. Even putting all networks in backbone area doesn't fix pinging problem. Subnets behind routers are always pingable and other IPs are not! The only pingable hop other than HQ is 172.16.2.6 (HAS's PPTP end to HQ). If yo...

Re: OSPF: No ping to backbone [SOLVED]

Thanks for spending time on this issue. I have already tried tracing and the only hops I see are 134.30 and 134.10. It seems that in some way, 134.30 passes packets destined to backbone back to 134.10 and because 134.10 is already told that these should be handled by 134.30, a loop is formed. Becaus...

Re: OSPF: No ping to backbone [SOLVED]

And which router has the IP 172.16.2.41? The non-pingable one has that as the next hop for basically all routes. Let me give you the map: HQ - (PPTP over Intranet) - HAS - (Wireless Link) - K1 - (PPTP over Intranet) - K2 And also: HQ - (PPTP over Internet) - K1Backup (Currently not installed) - (Ca...

Re: OSPF: No ping to backbone [SOLVED]

If this was the case, I would have received timeouts, not TTL expired. And, I'm sure that they do have routes to 192.168.134.0/24, as their routing tables explicitly show that. OK. Can you try pinging a backbone IP that is one hop away (on a neighboring router) and if it doesn't work then paste the...

Re: OSPF: No ping to backbone [SOLVED]

It can ping ONLY IPs bound to that router, and nothing else. Then, the most likely problem is that your other routers are probably missing a route to the 192.168.134.0/24 subnet, and can't get the reply packet back to the PC as a result. If this was the case, I would have received timeouts, not TTL...

Re: OSPF: No ping to backbone [SOLVED]

What else should I provide?
Can that PC ping a backbone IP that is actually bound to that router? Or it cannot ping any backbone IPs, including backbone IPs bound to that router?
It can ping ONLY IPs bound to that router, and nothing else.

Re: OSPF: No ping to backbone [SOLVED]

This is not enough information to help you. Saying that a PC in a subnet cannot ping anything without giving the subnet, IP address, and IP configuration of the PC does not help. What is the PC using as its default gateway? etc. My PC: IP: 192.168.134.248/24 GW: 192.168.134.30 Other PCs capable of ...

Hi I have configured OSPF on 6 routers and all work fine. But there is a strange problem (strange to me, ofcourse!).

Re: OSPF: Route not being filtered [SOLVED]

Is there a reason you are using redistribute-connected and redistribute-static for OSPF on all of the routers? This goes against normal OSPF design recommendations. I rarely need to enable these settings, and I am wondering why you felt the need to do so on all routers on your network. You may have...

Re: OSPF: Route not being filtered [SOLVED]

So, why doesn't this apply to 192.168.23.168/29 sunbet?! For logic's sake, don't say that it's because 192.168.0.0/16 is defined on HQ and 23.168/29 is defined on HAS!!! If you do, the only conclusion will be that in OSPF every router decides on its own, disregarding the structure of the entire netw...

OSPF: Filter routes using firewall

Hi.
I'm looking for a way to filter some of OSPF advertisements using firewall instead of route filters. The reason is that one of route filters doesn't work as expected. How can OSPF packets be matched by advertised prefix? Is there any way?

Hi I have two routers connected via PPTP running OSPF. This link is defined as a transit area. I want to set this path's cost to 100, in order to force traffic flow via my main link (this is backup). Main link has one more hop, causing traffic to be flown via this PPTP. I don't want to disable conne...

Hi.
My Hotspot on RB1100 AHx2 shows all dynamic trial users' stats zero (Uptime, Bytes/Packets In/Out):

Is this a bug (Currently 6.41 RouterOS)? Or I should do something to fix this?

First thanks for your reply. Every mentioned route is part of configuration on its corresponding router (first route is on 1100, second is on 951).
