recursion error routing Faribault, Minnesota

Syed Ali Sr. interface Serial8/0 ip address 192.168.16.1 255.255.255.252 ! Since 1 is a better metric than 2, they remove their entry from the routing table that points to R2 and insert an entry that points to the tunnel interface. Solution The solution is to add /32 static routes for the BGP neighbor, this way the static is chosen over the BGP route and there is an interface or next-hop IP

This will also mean that your tunnel interface will keep flapping until fixed.Let's take a look at a scenario in which recursive routing is being experienced. In this configuration, a static route 20.20.20.0/24 is configured pointing to the directly connected next-hop 192.168.16.2. OSPF has a lower (better) administrative distance than RIP, so the RIP entries will be removed and the OSPF entries will be installed…and the tunnel collapses. I will use one of the techniques to solve the problem in our setup: CopyrightprotectedbyDigiprove©2013-2016ReneMolenaar Rate this Lesson: You must be a member to vote We're Sorry, Full Content Access is

For simplicity, the diagram only shows two remote branches and the configuration only shows the headend and a remote branch.

It marks the route as recursive and removes it from the routing table. If a BGP keepalive message is once failed to be sent to BGP Peer because the transport link is down, the neighbor BGP Peer does not accept any further keepalive packets Join them; it only takes a minute: Sign up A “too much recursion” error in Firefox only sometimes? If I create a new tab and go to the same page(have two tabs of the same address) and then refresh the first tab two times then I get this error

Since this is a shorter prefix, the GRE-HEADEND router will eventually learn a better route via EIGRP and will try to use that to reach the tunnel destination address. Observe the routing table continuously for couple of minutes in order to see the flapping. Normally this is just a configuration error that people might make. interface Serial8/0 ip address 192.168.16.2 255.255.255.252 !

router eigrp 1 network 10.1.1.0 0.0.0.255 network 192.168.1.0 no auto-summary ! Still happening. These values are user configurable but Cisco recommends that it remains unchanged. Trying to reach the tunnel destination through the tunnel is a little problematic…it's a classic chicken and egg problem.

JamesHight commented Jun 27, 2012 @wagenet, yes its still happening. April 14, 2014 at 10:47 #13720 Rene MolenaarKeymaster Hi Alberto, You can also change the administrative distance for the OSPF routes that you use to reach the tunnel destinations: http://networklessons.com/ip-routing/how-to-configure-administrative-distance/ On the other hand you might encounter it on the CCIE lab exam 🙂 October 12, 2013 at 03:57 #13706 Gulzar Ahmed please check this ip entries (3.3.3.3) October 23, 2013 R2 is not part of the EIGRP domain.

Unfortunately, you died Problems from using Office 64bit Override and rename prototype in javascript Why do units (from physics) behave like numbers? Filter tunnel destinations from being sent/learned via the routing protocol When you have same addressing/subnets for tunnels as internal network (private WAN), the solution would be to filter tunnel destinations from What does "Game of the Year" actually mean? Add a specific static route in Rtr-A for the BGP peer IP address (20.20.20.20 in this case).

It's great whether you are new getting in the business, or just trying to understand a new networking technology to apply on the job. router bgp 1 no synchronization bgp log-neighbor-changes network 111.111.111.111 mask 255.255.255.255 neighbor 222.222.222.222 remote-as 2 neighbor 222.222.222.222 ebgp-multihop 2 neighbor 222.222.222.222 update-source Loopback1 no auto-summary !

I have personally emailed Rene on numerous times and he has always got back to me. March 20, 2014 at 17:22 #13713 Thom Hi Rene, Very interesting post and topics. Now the tunnel destination is no longer reachable and it collapses. Anyway, when the too much recursion error happens, it continues to happen until I restart Firefox.

Now we will enable RIP on the tunnel interface: R1(config)#router rip R1(config-router)#network 192.168.13.0 R3(config)#router rip R3(config-router)#network 192.168.13.0 As soon as we enable RIP on the tunnel interface you'll see this message I use Visio and the stencils from visiocafe.com, they make great stuff!

After activating RIP on the tunnel interface, R1 and R3 learn that they can reach each others loopback interface with a hop count of 1.

I've only lately been fortunate enough to have Networklessons.com as my guide. There are a number of options to do this: Don't advertise the tunnel destination IP address on the tunnel interface.

In our quiz, we don't have a private WAN and the tunnel destinations are public IP addresses, but the error exists in the command network 0.0.0.0 that is configured under the Sending 5, 100-byte ICMP Echos to 222.222.222.222, timeout is 2 seconds: .....
