question about bgp

I have a router configured with a prefix list that is updated very frequently. Is there any cisco bgp feature that will help avoid having to clear BGP soft every time that I update the filter? Thank you.

Troubleshooting Section

Do you think that it would be likely in the R&S exam that they would ask you any questions in the troubleshooting section where you would need to do a massive configuration in the exam, or will it mainly be break fix type scenarios where it’s already been configured?

Like say you had six routers in a scenario below, no routing protocols configured as of yet. Do you think it would be likely to get a task which says

“Users behind R6 cannot reach users behind R1″ “Configure the Network so that users in R6 can reach users in R1, ensure there is still reachability if any transit routers failed”

( R1 ) ——————- ( R2 ) | | | | ( R3 ) ——————– ( R4 ) | | | | ( R5 ) ——————– ( R6 )

IPSEC with NAT

Hi Experts,

I am trying to run IPSEC between an Internet router(with public IP address) and another router which got access to internet over a 3G mobile network. The 3G provider only assigns private address but is static NATed to a public IP address with in their cloud.

Please advise whether it is possible to run IPSEC between these 2 routers over the internet.

R1(IP=80.x.x.x) == INTERNET == 3G Network (where IP 10.1.1.1 is NAT ed to 90.x.x.x) == 3G Device with WAN IP – 10.1.1.1

Thanks, DN

quick question on eigrp updates

anyone have any clue in this regard???

Do not send EIGRP packets out any other interfaces; do not use the passive-interface command to accomplish this.
