i have R1(F0/0 :184.108.40.206 and R2 (F0/0:220.127.116.11) connected togather once i applied acl at R1 on the inbound direction i lost the ospf session and the ping between these 2 routers despite for the below ACL Config
acl 101 permit icmp host 18.104.22.168 host 22.214.171.124
acl 101 permit host 126.96.36.199 host 188.8.131.52
acl 101 permit ospf 184.108.40.206 host 220.127.116.11
acl 101 permit ip 192.168.1.0 0.0.0.15 any
ip access-group 101 in
R1 is my main router while R2 is my customer , i gave my customer the block 192.168.1.0/25 so i m going to implement some security like
RFC 1918 and RFC 2827 Filtering along with uRPF
pls lead me to the correct config and why the above acl didnt work?
Re: RFC 1918 and RFC 2827 Filtering along with uRPF
thanks for ur reply
what if i need to implement RFC 1918 and RFC 2827 Filtering along with uRPF towords my upstrem ISPs and i have phisical link between my and ISPs PoPs but as y now i peer with loopback address betwwen me and ISPs PoPs , so in this scenario how the acl config would be?
u forgot to mention in the acl the 192.168.1.0/25 i gave in the acl
