As shown in the figure, the asymmetric VLL FRR networking is used. AC
interfaces on PE 1, PE 2, and PE 3 are configured as follows:
Configuration of the AC interface on PE 1:
interface Pos3/0/1link-protocol ppp
undo shutdown
oam detect lcp-terminal notify lcp-terminal
ip address 208.1.1.1 255.255.255.0
ip address 208.2.2.1 255.255.255.0 sub
mpls l2vc pw-template pw1 13579 ip-interworking
mpls l2vc pw-template pw2 24680 ip-interworking secondary
mpls l2vpn oam-mapping
mpls l2vpn reroute immediately resume 0
Configuration of the AC interface on PE 2:
interface Pos1/0/3
link-protocol ppp
undo shutdown
ip address 208.1.1.2 255.255.255.0
mpls l2vc pw-template pw1 13579 ip-interworking
mpls l2vpn oam-mapping
Configuration of the AC interface on PE 3:
interface Pos1/0/0
link-protocol hdlc
undo shutdown
oam detect hello-stop notify hello-stop
ip address 208.2.2.2 255.255.255.0
mpls l2vc pw-template pw1 24680 ip-interworking
mpls l2vpn oam-mapping
Which of the following statements are true on the condition that IGP and MPLS are configured
correctly on the public network?
