最近学习PPPOE遇到了个问题 麻烦大神们 点拨下小弟
R2 上做了DHCP PPPOEAAA 并且跑了路由 R4上去认证 可是怎么也拿不到地址 我就在想直连可以获取地址 那跨广播域为什么就不行了(是不是由于DHCP 的helper-address但是做了还是没起作用) R2 R3R1就跑普通路由 hostname RACK32R2 enable password ccie aaa new-model aaa authentication ppp ccnp local-case ip dhcp excluded-address 172.16.3.1 ip dhcp pool ccie network172.16.3.0 255.255.255.0 bba-group pppoe ccna virtual-template 1 ! ! interface Loopback1 ip address 2.2.2.2255.255.255.0 ! interface FastEthernet0/0 ip address172.16.12.2 255.255.255.0 duplex auto speed auto pppoe enable groupccna ! interface FastEthernet0/1 ip address172.16.23.2 255.255.255.0 duplex auto speed auto ! interface Virtual-Template1 mtu 1492 ip address172.16.3.1 255.255.255.0 peer default ipaddress dhcp-pool ccie ppp authenticationpap callin ccnp(即使NO掉这条还是没办法拿到地址) ! router eigrp 1 network 172.16.0.0 no auto-summary R4 hostname R4 interface FastEthernet0/1 ipaddress 172.16.14.4 255.255.255.0 duplex auto speed auto pppoe enable group global pppoe-client dial-pool-number 1 ! interface Dialer1 mtu1492 ipaddress negotiated iphelper-address 172.16.3.1 encapsulation ppp dialer pool 1 ! router eigrp 1 network 172.16.0.0 noauto-summary ip route 0.0.0.0 0.0.0.0 Dialer1
