WebThe slow BGP convergence dictates a two-protocol design of an ISP network: An internal routing protocol -- most often, Open Shortest Path First ( OSPF) or Intermediate System to Intermediate System (IS-IS) -- is used to achieve fast convergence for internal routes, including IP addresses of BGP routers. BGP is used to exchange internet routes. WebJun 30, 2024 · NPt makes perfect sense for SOHO IPv6 Multi-WAN deployments. The likelihood that a home or small business end user will have their own provider-independent IPv6 space and a BGP feed is very small. In these cases, the firewall can utilize a routed prefix from multiple WANs to function similarly to Multi-WAN on IPv4.
