prevent DDOS in low speed link

Hi all:

Should we configure some Qos feature in a low speed serial link to prioritize the ospf routing packet in a low speed FR link in case of under DDOS attack. If could , how could we do the configure ?

Thanks

Re: prevent DDOS in low speed link

For prioritizing routing update on FR network, one way I can think of is setting the discard Eligible bit on all traffic except routing update.

Hope this helps,
