    Jan 04, 2006 · There is a fundamental problem with IPsec tunnels and dynamic routing protocols. Dynamic routing protocols rely on using IP multicast or broadcast packets, but IPsec does not support encrypting multicast or broadcast packets. The current method for solving this problem is to use generic routing encapsulation (GRE)...

    May 01, 2015 · If you’re using dynamic routing, you don’t even have to do that, as the routing protocols do it for you. Compared to the IPsec method of maintaining matching, phase-2 selectors where you have to add/remove an exponentially increasing number of selectors as networks change, this is a huge win in terms of time savings and reducing ...Location: 111 W.

RFC 3884 - Use of IPsec Transport Mode for Dynamic Routing

    https://tools.ietf.org/html/rfc3884
    The topology of an IPsec VPN commonly consists of IPsec tunnel mode virtual links, as required by the IPsec architecture when the communicating peers are gateway pairs, or a host and a gateway [ 1 ]. However, this current required use of IPsec tunnel mode can be incompatible with dynamic routing [ 3 ].Cited by: 18

    IPSec supports the encryption of unicast IP traffic only. Therefore, routing protocols like Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (OSPF) and non-IP traffic like Internetwork Packet Exchange (IPX) and AppleTalk are unable to be encrypted using IPSec. For a workaround, encapsulate such traffic in Generic Routing Encapsulation (GRE) before encryption, using a GRE over an IPSec configuration…
