Example for Configuring IPsec for RIPng
NOTE:
For RIPng, OSPFv3, and IPv6 BGP, IPsec is configured similarly. For detailed configuration, refer to
RIPn
Configuration, OSPFv3 Configuration
and
IPv6 BGP Configuration
in
IP Routing Volume
.
Network requirements
As shown in Figure 8, Device B connects Device A and Device C. These Devices learn IPv6 routing
information through RIPng.
• RIPng packets between two devices are transmitted through an IPsec tunnel.
• The security protocol to be used is ESP, encryption algorithm is DES, and authentication algorithm
is SHA1-HMAC-96.
