Advertising Primary IP Address<\/span><\/strong><\/p>\n\n\n\n

On a vPC enabled leaf or border leaf switch, by default all Layer-3 routes are advertised with the secondary IP address (VIP) of the leaf switch VTEP as the BGP next-hop IP address. Prefix routes and leaf switch generated routes are not synced between vPC leaf switches. Using the VIP as the BGP next-hop for these types of routes can cause traffic to be forwarded to the wrong vPC leaf or border leaf switch and black-holed. The provision to use the primary IP address (PIP) as the next-hop when advertising prefix routes or loopback interface routes in BGP on vPC enabled leaf or border leaf switches allows users to select the PIP as BGP next-hop when advertising these types of routes, so that traffic will always be forwarded to the right vPC enabled leaf or border leaf switch.<\/p>\nhttps:\/\/www.cisco.com\/c\/en\/us\/td\/docs\/switches\/datacenter\/nexus9000\/sw\/93x\/vxlan\/configuration\/guide\/b-cisco-nexus-9000-series-nx-os-vxlan-configuration-guide-93x\/b-cisco-nexus-9000-series-nx-os-vxlan-configuration-guide-93x_chapter_01000.html<\/a><\/cite><\/blockquote>\n\n\n\n
