In ddr situation,interesting traffic is defined with dialer-list.After the bakcup link is up triggered by interesting traffic,can other traffic different from interesting traffic get through the backup link?Expect your answers.
I believe that non-interesting traffic can get through once the link is brought up. The link can't be kept up by non-interesting traffic, however, AFAIK -- it will still go down if interesting traffic isn't seen within the timeout period.
