BGP Support for TCP Path MTU Discovery per Session


BGP Support for TCP Path MTU Discovery per Session


Border Gateway Protocol (BGP) support for Transmission Control Protocol (TCP) path maximum transmission unit (MTU) discovery introduces the ability for BGP to automatically discover the best TCP path MTU for each BGP session. TCP path MTU discovery is enabled by default for all BGP neighbor sessions, but you can disable, and subsequently enable, the TCP path MTU globally for all BGP sessions or for an individual BGP neighbor session.
