Remediation

Vendor Workaround

The workaround is to disable the Dynamic Path Selection (DPS) service inside BGP LinkState by disabling the feature toggle. Note this should be done on affected non AWE platforms only. 1. Enter "bash" shell under EOS prompt 2. sudo sh -c 'echo "BgpLsConsumerDps=0" > /mnt/flash/toggle_override; echo "BgpLsProducerDps=0" >> /mnt/flash/toggle_override' 3. Reload the switch or router
