EGRESS NODE PROTECTION IN EVPN ALL-ACTIVE TOPOLOGY |
摘要 |
In general, techniques enable an intermediate router to perform node protection for one or more other PE routers operably coupled to the intermediate router in active-active mode in an EVPN. The techniques may include configuring the intermediate router, which is positioned within an a service provider network between a remote provide edge router and at least two provider edge (PE) routers operating in active-active mode in an Ethernet Virtual Private Network (EVPN), to operate in a passive mode in which the intermediate router detects Ethernet Auto-Discovery (AD) routes without performing layer two (L2) address learning for the EVPN. The techniques may include installing a primary route to a protected router and a backup route from the intermediate router to a PE router other than the protected router, and in response to a link failure, forwarding network traffic using the backup route without requiring reprogramming the forwarding unit. |
