We have 3 - MX450 placed as HUB (EMEA, APAC, LATAM) with resilience in our network, from last few days, we are facing an issue :
>Issue: Flapping is observed at all HUB site at almost same time for both Auto-VPN & e-bgp peering got teared & bgp usually gets automatically established after few minutes.
Topology:-
External ISP <--> BGP Peering <--> OUR HUB CE <--> BGP Peering (advertising ebgp routes with Meraki HUB) <--> Regional HUB Meraki <--> Site Meraki's
TAC Response: Issue frequently occurring as MX450 is incapable of holding more than 150 E-bgp Down.
Query - we are receiving these e-bgp routes that are somewhere around 1000 from last 1 year, so how suddenly now this issue is occurring ?
