[c-nsp] mlppp icmp monitoring

[George Smith]

Hi,

Before upgrading to 12.3(16) sp, I was able to monitor serial interfaces
with icmp by giving ip addresses to the serial interfaces used in the
mlppp bundle on 12.3(1) enterprise plus. Interface configuration is below.
interface Serial5/3:0
  ip address 192.168.1.1 255.255.255.254
 no ip redirects
 no ip proxy-arp
 encapsulation ppp
 load-interval 30
 no fair-queue
 no cdp enable
 ppp multilink
 ppp multilink group 1
end

Any ideas ?
