  • Device problem occurs on (all are ar71xx devices)

2x NETGEAR WNDR3700
3x WD My Net N750
1x GL AR150

  • Software versions of LEDE release, packages, etc.

LEDE Reboot 17.01-SNAPSHOT r2993+234-ef5cb96

  • Steps to reproduce

I setup 6 routers, wan has a static IPv4, wan6 set to dhcpv6. I use odhcpd in relay mode because our network does not do prefix delegation. All routers have separate physical internal LAN networks, but they share the same physical external WAN/WAN6 network. After approx 8-12 hours the symptoms occur. If I stop odhcpd on all routers, the problem goes away.

When the problem occurs, ipv6 appears to work normally. odchpd hogs the cpu, anywhere from 20%-35% constant. Also logread reports many addresses are 'forgot' and 'learned' (see below)

config dhcp 'lan' option interface 'lan' option start '100' option limit '99' option leasetime '12h' #option dhcpv6 'relay' option ndp 'relay' option ra 'relay'

config dhcp 'wan'
option interface 'wan'
option ignore '1'

config dhcp 'wan6'
option interface 'wan'
#option dhcpv6 'relay'
option ndp 'relay'
option ra 'relay'
option master '1'

config odhcpd 'odhcpd'
option maindhcp '0'
option leasefile '/tmp/hosts/odhcpd'
option leasetrigger '/usr/sbin/odhcpd-update'

Sample traffic from the WAN using 'tcpdump -i eth0 icmp6'

NOTE: my routers end in:

70b7
77a8
2c21
71fb
4e2e
652a

NOTE: It looks to me like my 5 remote routers seem to be repeating every request to this router.

This is a tcpdump with just two routers running odhcpd... I stopped odhcpd on all 6 routers, then started it again on 2:

The two routers running odhcpd have IPv6 suffixes:

2c21
40

Updated odhcpd to git HEAD version in trunk (https://git.lede-project.org/?p=source.git;a=commit;h=c45ef702ff3d4fd79b788823719cda356b9088c5); could you give it a try in your setup ?

I only had time to test one router on Friday, but yes the flooding problem was gone, and network traffic worked normally. I can test further on monday.

I built 17.01 with this version of odhcpd, and installed in on 7 production routers, and the problem seems to be resolved.

I got this installed on several routers in my dept... and it does look like there is now some kind of problem setting up connections. Looks like odhcpd does not reliably respond to neighbor solicitations. Will see what else I can find...

OK restarted odhcpd on the affected router and all appears fine again.. I will keep monitoring...
