Hello, this is the network that I'm using:I'm using NAT (PAT to be exact) on Edge-A and Edge-B routers. I put static routes on ISP_1 and ISP_2 for address 198.133.219.5/32 (ISP_1) and 198.133.220.5/32 (ISP_2) respectively, so they can return the pack...

Hello, I'm trying to understand how BGP aggregate-address command actually works. The network is shown below: The whole network is configured and it's ready to go. On D1 router from BGP 64530 I managed to aggregate 4 IP addresses: 10.10.154.20810....

Hello! I have a few questions regarding BGP network and how it works in general. Many of you probably will recognize this network since I had 2 topics here already. The network is given below: D1, D2 and D3 router have OSPF process between and the...

Hello, I have this network where D1, D2 and D3 routers are configured as iBGP. Network works just fine until I do the command: neighbor x.x.x.x update-source loopback 0 on each router. Once this is done, routers begin to shutdown their neighbors af...

Hello! Routers with red arrow are the ones that are using a basic static default route of 0.0.0.0 to their respective neighbors. D1,D2,D3 are iBGP connected with no additional of next-hop-self or update-source commands. D2 and OfficeA-1 routers are c...

Hey David. I have now an issue here. After doing the send-community and route-map SET_NO_EXPORT for 90.0.0.1 neighbor and C3 neighbor, now they do not get any route from D1 at all. 10.255.255.0 is not sent together with 192.168.150.0 and 192.168.100....

Hello, I'm truly sorry for such a late response but I was busy and haven't been able to do the network properly until today. I must say that BGP aggregation is very hard indeed to do and it took me quite some time to understand it. I did follow yo...

Thank you very much! Now it is more clear about what I have to do. Your replies are always helpful.

There's only one single static route of 10.255.255.0 from D3. That one is redistributed yes. That route goes up to the 10.10.14.0 network because there is a router there. D3 uses a static route to reach his LAN network. Router on that other side is u...

@David Ruess @Harold Ritter Thank you very much for your detailed explanation. Here is the current image so you get the idea of what is happening. On routers D1, D2 and D3, I removed all neighbor commands. Then I added the neighbor commands again b...
