Enabling MD5 authentication for TCP connections
IPv6 BGP employs TCP as the transport protocol. To enhance security, configure IPv6 BGP to perform
MD5 authentication when establishing a TCP connection. If the authentication fails, no TCP connection
can be established.
Follow these steps to enable MD5 authentication for TCP connections:

NOTE:
•
The MD5 authentication for establishing TCP connections does not apply to BGP packets.
•
The MD5 authentication requires that the two parties have the same authentication mode and password
to establish a TCP connection; otherwise, no TCP connection can be established due to authentication
failure.
Applying an IPsec policy to an IPv6 BGP peer or peer group
To protect routing information and defend attacks, IPv6 BGP can authenticate protocol packets by using
an IPsec policy.
Outbound IPv6 BGP packets carry the Security Parameter Index (SPI) defined in the IPsec policy. A device
uses the SPI carried in a received packet to match against the configured IPsec policy. If they match, the
device accepts the packet; otherwise, it discards the packet and will not establish a neighbor relationship
with the sending device.
Configuration prerequisites
Before applying an IPsec policy to a peer or peer group, complete following tasks:
•
Create an IPsec proposal
•
Create an IPsec policy
For more information about IPsec policy configuration, see
