Hello,
Since a upgrade in IOS XE 3.0.9, our ASR 1002 have a problem with the DHCPDISCOVER.
When i do some debug
asr1002#debug ip udp port 67
UDP packet debugging is on
asr1002#debug ip udp port 68
UDP packet debugging is on
And i do some tests with an linux utility like "socat", we obtain:
May 17 15:51:33.239 METDST: UDP: rcvd src=192.168.7.78(34747), dst=192.168.7.1(68), length=14
May 17 15:51:41.837 METDST: UDP: rcvd src=192.168.7.78(40462), dst=192.168.7.255(68), length=14
with the destination adress 192.168.7.255
But with 255.255.255.255, nothing !
The configuration of interface:
interface GigabitEthernet0/0/0.674
description Vlan Pavillons
encapsulation dot1Q 674
ip address 192.xxx.xxx.xxx 255.255.255.248 secondary
ip address 192.168.7.1 255.255.255.0
ip helper-address 10.xx.xx.xx
ip helper-address 10.yy.yy.yy
ip information-reply
ip nat inside
ip pim sparse-mode
ip virtual-reassembly
zone-member security FAI
ip policy route-map BANLIEU
end
Somebody have an idea ? Thanks for help
PS:
a "show ip dhcp server statistics" sho that the dhcpdiscover are not seen !!!!
