Hi,
Trying the ASR 9006 IOS XR 6.4.2 as a BNG for the first time. DHCP Proxy does not work with Ambiguous VLAN interface.
Configuration:
dhcp ipv4
profile IPoE_DHCP proxy
helper-address vrf default 192.168.2.228 giaddr 192.168.2.55
broadcast-flag policy unicast-always
relay information policy keep
relay information option allow-untrusted
!
interface Bundle-Ether19.3333 proxy profile IPoE_DHCP
!
dynamic-template
type ipsubscriber IPoE
timeout idle 600
accounting aaa list default type session periodic-interval 60 dual-stack-delay 1
ipv4 verify unicast source reachable-via rx
!
!
interface Bundle-Ether19.3333
ipv4 point-to-point
ipv4 unnumbered Loopback50
arp learning disable
ipsubscriber ipv4 l2-connected
initiator dhcp
!
encapsulation ambiguous dot1q 3333 second-dot1q 1405-1420
!

match protocol dhcpv4
end-class-map

end-policy-map

When DHCP DISCOVER arrive in be19.3333 second tag 1420 I see in debug log

Without ambiguity

all is Ok.
I've seen a few examples, but nowhere was there a problem.What is wrong in my config&
