<div dir="ltr">John,<br><br>What would most likely be a better solution for both solutions is to assign the customer a fixed IP allocated from RADIUS when they connect over L2TP (I assume PPP...)<br>This will allow you to have a static BGP session with the statically allocated IP address.<br>
<br>Another option is to look at the BGP dynamic neighbors feature:<br><a href="http://www.cisco.com/en/US/docs/ios/12_4t/ip_route/configuration/guide/brbpeer.html#wp1131929">http://www.cisco.com/en/US/docs/ios/12_4t/ip_route/configuration/guide/brbpeer.html#wp1131929</a><br>

Hi,<br>
<br>
I've got two design questions:<br>
<br>
<br>
1. Is it possible to map a net via L2TP (IPv4 PI Space) to a client, which<br>
comes from a dynamic IP Address? E.g he has RIPE PI Space AAA.BBB.CCC.DDD<br>
and as he connects, routers will allow traffic to his network<br>
AAA.BBB.CCC.DDD and BGPv4 will recognize an will aloe route servers to be<br>
changed...<br>
<br>
2. Is it possible to have the IPSec with (1.)?<br>
<br>
<br>
Cheers,<br>
<br>
<br>
John<br>
