Reindent issues
by Bingen Eguzkitza 22 Aug '17

22 Aug '17

Hi, I was trying to apply instructions here (rebase case): https://github.com/FRRouting/frr/wiki/Reindenting but for stable/3.0, and maybe I'm missing something, but it's not working as I would expect. To make it easy to reproduce, and to discard causes related to my branch, what I'm doing is: $ git checkout reindent-3.0-before $ git checkout -b test_reindent $ git cherry-pick reindent-3.0-before Now I have a new branch identical to reindent-3.0-after, can be checked with: $ git diff test_reindent reindent-3.0-after I do this so the script treats it as a new non-rebased branch. Then: $ python git-reindent-branch.py test_reindent I would expect that reindented branch is still identical to reindent-3.0-after, but it's not: $ git diff --stat reindented-branch reindent-3.0-after (...) <- see attached for details 598 files changed, 269745 insertions(+), 244747 deletions(-) How was the reindentation for stable-3.0 done? Was this script used? Thanks, ßingen.

Issue with route-map on route-reflector?
by François Serman 22 Aug '17

22 Aug '17

Hi, First of all, I hope this is the appropriate ML :) I have an issue with route-map applied to reflected route, in the following scheme: A [ exaBGP ] --- advertises prefixes ---> B [ FRR ] --- appends attributes ----> C [ FRR ] 10.1.0.1 10.2.0.1 10.3.0.254 A advertises prefixes (1.1.1.1-24/32 with next hop 1.2.3.4). B is supposed to set a community (I've added local-pref and changed the next-hop to make for tests purposes). C is supposed to have an aggregated view of the prefixes decorated with the communities. My issue is : A's advertised-routes output seems OK (next hop, local pref) but only the local network (as in bgp router id block) is actually changed. I didn't find anything in the documentation about that. I've only found a mention in the cisco documentation (https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bgp/configuration…) : "The use of set clauses in outbound route maps can modify attributes and possibly create routing loops. To avoid this behavior, most set clauses of outbound route maps are ignored for routes reflected to iBGP peers. The only set clause of an outbound route map on a route reflector (RR) that is acted upon is the set ip next-hop clause. The set ip next-hop clause is applied to reflected routes. " Is there something I'm missing? Also, I've been checking who was right using tcmdump, attached to this email. Here is B's config: router bgp 65001 bgp router-id 10.2.0.1 bgp log-neighbor-changes neighbor my_route_advertisers peer-group neighbor my_route_reflectors peer-group neighbor my_route_reflectors remote-as internal neighbor my_route_reflectors description route-forwarder neighbor 10.3.0.254 remote-as 65001 neighbor 10.3.0.254 peer-group my_route_advertisers neighbor 10.1.0.1 peer-group my_route_reflectors ! address-family ipv4 unicast network 192.168.21.0/24 neighbor my_route_advertisers route-map deny-in in neighbor my_route_reflectors route-reflector-client neighbor my_route_reflectors route-map deny-out out neighbor 10.3.0.254 route-map apply-community out exit-address-family vnc defaults response-lifetime 3600 exit-vnc ! route-map apply-community permit 10 set community 65001:1010 set ip next-hop 8.8.8.8 set local-preference 10 ! route-map deny-in deny 5 ! route-map deny-out deny 5 and its advertised routes: # sh ip bgp neighbors 10.3.0.254 advertised-routes BGP table version is 25, local router ID is 10.2.0.1 Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, i internal, r RIB-failure, S Stale, R Removed Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path *> 1.1.1.1/32 8.8.8.8 0 10 0 i .... *> 1.1.1.24/32 8.8.8.8 0 10 0 i *> 192.168.21.0 8.8.8.8 0 10 32768 i Total number of prefixes 25 And now, C's config: router bgp 65001 bgp router-id 10.3.0.254 bgp log-neighbor-changes neighbor my_route_advertisers peer-group neighbor my_route_reflectors peer-group neighbor my_route_reflectors remote-as internal neighbor my_route_reflectors description route-forwarder neighbor 10.4.0.254 remote-as 65001 neighbor 10.4.0.254 peer-group my_route_advertisers neighbor 10.2.0.1 peer-group my_route_reflectors neighbor 10.2.0.2 peer-group my_route_reflectors ! address-family ipv4 unicast neighbor my_route_advertisers route-map deny-in in neighbor my_route_reflectors route-reflector-client neighbor my_route_reflectors route-map deny-out out neighbor 10.2.0.1 soft-reconfiguration inbound exit-address-family vnc defaults response-lifetime 3600 exit-vnc ! route-map deny-in deny 5 ! route-map deny-out deny 5 rr# show ip bgp neighbors 10.2.0.1 received-routes BGP table version is 0, local router ID is 10.3.0.254 Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, i internal, r RIB-failure, S Stale, R Removed Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path *> 1.1.1.1/32 1.2.3.4 0 100 0 i ..... *> 1.1.1.24/32 1.2.3.4 0 100 0 i *> 192.168.21.0 8.8.8.8 0 10 0 i Total number of prefixes 25 Thanks!

Vty password is not set error

Hi All, I was successful in installing quaga and got it working fine. Then I decided to try frr. I followed all the instructions mentioned in the link below. https://github.com/FRRouting/frr/blob/master/doc/Building_ FRR_on_Ubuntu1604.md Now when I try to telnet to zebra, it says "Vty password is not set". telnet localhost zebra Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Vty password is not set. Connection closed by foreign host. I have added following config to /etc/frr/zebra.conf but that is not helping. sudo cat /etc/frr/zebra.conf [sudo] password for sidhesh: !
