EIGRP Does not Learn EIGRP External Route #1006

Open mTaleqani opened 7 years ago

mTaleqani commented 7 years ago

i did redistribute ospf routes into eigrp in a cisco router that has an EIGRP adjacency with FRR, although cisco sent eigrp external routes in an update packet and frr acked the updates, but the external routes are not shown in frr.

@mTaleqani Just another issue that needs to be fixed :) On my list of stuff to do eventually

I'm testing on new Ubuntu 17.04 and it crashes quite quickly with

@mTaleqani @lucize let's try #1011

diivious commented 7 years ago

There is a fair bit of work needed for EIGRP to support external routes. #1011 only fixes the crash issue by essentially "discarding" the external routes.

donaldsharp commented 7 years ago

Yes #1011 fixes the crash not the external route issue

diivious commented 7 years ago

by the way - just looked, and the change to discard externals is not in eigrp_update/query.c So at L259 if you get EIGRP_TLV_IPv4_EXT, you will crash still...

lucize commented 7 years ago

the crash is gone, eigrp routes are in, no external, but hey..

For me it is still crashing when eigrp external route is received.

Tests are done on frr master.

try to add #1014 git pull origin pull/1014/head

donaldsharp commented 7 years ago

I've pushed in #1014 let us know if this fixes the crash

mTaleqani commented 7 years ago

by using #1014 , no eigrpd crash happens but still no eigrp external routes learned.

donaldsharp commented 7 years ago

@mTaleqani yep, we are working on handling of external routes, hopefully within a week.

gtg625n commented 4 years ago

Good evening guys,

Probably linked to that issue: I am running a FRR, directly connected to a CSR1000v (from Cisco). The EIGRP neighborship is established well between them. However, the FRR does not learn the routes from its CSR peer EIGRP that are external (learned from the BGP process). The other way around works well, that is to say, the CSR learns well the EIGRP routes from the FRR and redistributes them OK into its BGP process.

The network diagram is attached.

The config of the FRR is: (extract) router eigrp 101
eigrp router-id 192.168.105.1
network 172.16.1.0/24
network 192.168.105.1/32

The config of the CSR is: (extract): router eigrp 101 ! address-family ipv4 vrf SERVICE-A autonomous-system 101 redistribute bgp 64512 metric 10000 10 200 5 1500 network 172.16.1.0 0.0.0.255 eigrp router-id 172.16.1.2 exit-address-family

Thank you in advance.

gtg625n commented 4 years ago

Ah, and the version of the FRR is: frr version 7.2-dev-MyOwnFRRVersion
frr defaults traditional

vnpraveendesu commented 3 years ago

@mTaleqani yep, we are working on handling of external routes, hopefully within a week.

@donaldsharp Handling of external route support is added in the FRR EIGRP code? If not, any suggestions what is involved in adding this support. I have some understanding of FRR EIGRP code. I can look into adding this support, but will need some pointers to get started.

lucize commented 3 years ago

@vnpraveendesu it would help more if you can find why the daemon crashes very often with lots of routes and cisco devices

@lucize can you share the topology

eigrp inserts the poison reverse( infinite delay/bandwidth) routes advertised by the cisco router ( Split horizon enabled) into the topology table as well as routing table eigrp crashes when the update/query receive for poison reverse routes.

Please check the output of "Show ip route eigrp"

lucize commented 3 years ago

@vnpraveendesu does the attached file helps ?

I don't have access on all switches and routers but the one I have are like:

maybe this works in your environment, for me it seems it's till a wip, https://github.com/diivious/eigrpd

last update eigrpd is partially working - gets only the default route, but have other neighbors with many routes and crashing late:
