Hi,
I stumble upon problem that look like broken dhcp-realy.
I have simple configuration with CCR-1032:
172.30.1.1/24(eth1-vrrp)<-CCR->10.0.0.1/16(ether3).
/interface vrrp
add interface=vlan500 name=vrrp-vlan500 priority=220
/ip address
add address=172.30.1.2/24 interface=vlan500 network=172.30.1.0
add address=172.30.1.1/24 interface=vrrp-vlan500 network=172.30.1.0
System is VRRP master:
/interface vrrp pr
Flags: X - disabled, I - invalid, R - running, M - master, B - backup
# NAME INTERFACE MAC-ADDRESS VRID PRIORITY INTERVAL VERSION V3-PROTOCOL
0 RM vrrp-vlan500 vlan500 00:00:5E:00:01:01 1 220 1s 3 ipv4
DHCP-server is 172.30.1.11
My dhcp-relay config:
add add-relay-info=yes dhcp-server=172.30.1.11 disabled=no interface=ether3 local-address=10.0.0.1 name=WiFi relay-info-remote-id=""
It worked properly for few hours and then after one night local-address in DHCP packets is always from ether1-physical (172.30.1.2) instead 10.0.0.1
Here what I see on dhcp server tcpdump:
# tcpdump -ni eth2 port 67
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 65535 bytes

Creating/removeing dhcp-relay setup doesn’t help.
Anyone have idea what is wrong with my setup ?
