Sample Diagram here.
The dual ISPs network that I am working has an interesting setup.
In Router 1, here is a partial config
ip route 67.29.128.153 255.255.255.255 50.50.50.2
partial show ip route
Gateway of last resort is 67.29.128.153 to netwo...
Trying to analyze a dual ISPs BGP configurations. This is for both Lumen and AT&T ISPs
1.I have the following BGP community.
set community 202:110 202:202
How do I find out what they maps to? Is there a way to look those up?
2. We have AS number pre...
Simplified example diagram.
We currently have dual ISPs, dual routers, dual firewalls with single AS with two subnets. As an example, 10.10.10.0/24 and 20.20.20.0/24. Both ISPs passes BGP default route to the routers. Both routers runs HSRP.
Ser...
I have the following scenario. If I need to have Server2, Server3, and Server 4 access Server1 without seeing each other, what is the best way to do this using VRF? 6509 is currently the layer 3 gateway. There are also other workstations that con...
I have the following switches, how do I know if they support VRF? Don't need MPLS.
Do I simply look for VRF-Lite? Tried Cisco feature navigator, some does not show up
WS-C3508G-XL-EN - c3500xl-c3h2s-mz.120-5.WC13.bin
WS-C3560-24PS-S - c3560-advipse...
Got it. Thank you for the explanation.
There were some errors in the diagram. Here is an updated diagram. I remove the switches to simplify the diagram. Both Router1 and Router2 are in AS 400. However, they do not have each other as BGP neighbo...
Thank you for the fast response. Currently Router 1 and Router 2 communicate with Firewall 1 and 2 via BGP.
Where should this preference be set? Router1? Firewall 1? using weight?
If I want incoming traffic from Server 2 to use ISP1 for subnet 10....
This is a simplified diagram. The actual layout is actually more complicated than this.
Suppose the need is to accomplish this using VRF, how would one do this?
I thought "switchport protected" is only local to the switch
It turns out that the VLC GUI TTL has a bug. Even if I specify TTL of greater than 10, it still shows TTL of 1 when using wireshark. I end up using VLC command line which works.
