Hi there,
I'm a realtive Cisco newbie, and I have a new edge router in a network with the following characteristics:
Cisco 6509 -- Flex-WAN module, 4 ports
2 ISP's 2 Multilinked T1's BGP enabled 3 Private Network SegmentsI want to enable Ingress and Egress Filtering to protect against IP Spoofing.
Let's say these are the addresses for my multilinked T1's:
ISP1 - 55.55.55.254 255.255.255.252 ISP2 - 66.66.66.254 255.255.255.252
My Network Block looks like this:
77.77.77.0 255.255.255.0My private segments look like this:
10.1.0.0 /16 10.2.0.0 /16 10.3.0.0 /16I was wondering if somone could give me assistance with how to construct my ACL's based on my network information and help me make sure the syntaxt is correct.
Your help would be appreciated.
Regards,
