Here is sample tutorial on how to configure External Border Gateway Protocol (EBGP) between Huawei Router and another router. I will focus on the configuration of the Huawei router (RouterA). Fig.1.1 Procedure: 1. Configure the Loopback IP address a. Enter system view command: system-view <RouterA>system-view Enter system view, return user view with return command. <RouterA>interface LoopBack0 <RouterA>description RouterA Loopback0 <RouterA>ip address 172.16.1.1 255.255.255.255 <RouterA>quit Verify: <RouterA>display current-configuration interface LoopBack 0 2. Configure the P2P(point to point) IP, we will assume…

We are going to configure VRRP between the 2 pairs of routers and the expected behavior, setup as per below: Setup: 1. Routers PE1,PE2,FW1 and FW2 are connected to the same Layer 2 Switch and belongs to the same VLAN. 2. L2-Switch will just function as Layer 2 switch (subnet 192.168.2.240/29) 3. VRRP is configured between PE1 & PE2 3. VRRP is configured between FW1 & FW2 Fig.1 IP & VRRP Configuration: L2-SWITCH L2-SWITCH#conf t a. Setup access VLAN…
Static Route Configuration Examples in Juniper for BGP aggregated prefix advertisements In order to advertise the aggregated routes (and default routes) via BGP, it should exists in the routing table, that’s the #1 rule. If these summarized routes (/16) are not existing and only smaller subnets are learned via the IGP(e.g. OSPF,IS-IS), then configure static route and next hop e.g. Null0. Configuration: routing-options { graceful-restart; rib inet6.0 { static { route fd41:c8be:2153:f400::/64 discard; route ::0/0 { discard; no-install; static {…
Originating BGP advertisement can be configured to any iBGP peer router. Here’s the sample configuration of originating BGP routes and community tagging in Juniper. Assuming these are the summarized prefixes that you want to advertise via BGP. 111.111.0.0/16 222.222.0.0/16 Configuration: routing-options { graceful-restart; router-id 1.1.1.1; autonomous-system 11111; protocols { bgp { group RR-IBGP { type internal; description RR-IPv4; local-address 192.168.100.6; family inet { unicast; } authentication-key “$1$N3tBioBwfdFsFVwgoGDh.3C0oL”; ## SECRET-DATA export bgp-statement; neighbor 192.168.100.5 { description iBGP to Route Reflector; }…
Static Route Configuration Examples in Cisco (IOS-XR) for BGP aggregated prefix advertisements In order to advertise the aggregated routes (and default routes) via BGP, it should exists in the routing table, that’s the #1 rule. If these summarized routes (/16) are not existing and only smaller subnets are learned via the IGP(e.g. OSPF,IS-IS), then configure static route and next hop e.g. Null0.
