Flapping PPPoE Virtual Access Interface

pujan96

Hi Guys,

Ive set up a PPPoE lab on GNS3 with a customer router and an ISP router. I am having the virtual access interfaces flapping up and down at regular intervals, When up and working I have a dialer interface line status of up and up (spoofing), even when the virtual access is down the dialer is up.

However when the Virtual access is down I get the following log message:
*Jul 20 10:26:26.347: %DIALER-6-UNBIND: Interface Vi2 unbound from profile Di1
*Jul 20 10:26:26.395: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access2, changed state to down
And in the PPPOE show session command the virtual access interface is listed as shut down.

Here is the config for the ISP and customer routers:
Cust1 Router
interface FastEthernet0/0
no ip address
duplex full
pppoe enable group global
pppoe-client dial-pool-number 1

interface Dialer1
mtu 1492
ip address negotiated
encapsulation ppp
dialer pool 1
dialer idle-timeout 0
dialer persistent
ppp authentication chap callin
ppp chap hostname Cust1
ppp chap password 0 ciscopress
