Hi, I have some problems with BGP graceful restart on ASR9010 when SSO occurs.
I have ASR9010 which performs SSO, and Catalyst6504 as a peer device.
BGP graceful restart is enabled on both sides, and I confirmed that BGP graceful restart capability has advertised and received on both devices.
However, when A9K performs RP switchover(with a command”redundancy switchover”), it seems that BGP GR is not working properly.
Strangely, traffic from A9K towards C6K isn’t affected. Only traffic from C6K is lost.
Physical links between the devices are connected directly on RP on A9K, which I suspect the reason but not sure.
If there’s anything I can try or I should check, please let me know.
thanks.
Kei
