[BGPCEP-746] Too much BGP-IPv4 Flow Specification routes cause ODL dead

Tue, 24 Jan 2023 17:50:23 +0000

State OpenDaylight version: Carbon SR2
I use BGP-IPv4 Flow Specification programming to post routing.The ODL is OK when I post less than 2000 routing to it.Without the limit of transferring speed, the crashed outbreak may strike from each 2000 sendings based on the protocol of sending IPv4 Flow Specification routing.The crashed outbreak may occur by sending each one in a second up to 10,000 times.

3.The picture is how to post IPv4 Flow Specification routing.
