Thank you so much Philip!
1) For the first issue, we still need to have the "default-originate" on the secondary site, am I correct?
2) The BGP configuration of each site is" neighbor x.x.x.x remote-as 38605"- 38605 is ISP ANS. The neighbor is not pointed to the router in primary data center or secondary data center. Can you please elaborate how you configure with local preference or weight?

We have two data centers, and 20 remote sites in MPLS clould via BGP. Currently the router in primary data center injects a default route into all remote MPLS routers via default originate under its BGP process (i.e- neighbor x.x.x.x default-originate). Here is what I like to implement.
1) If the MPLS router in the primary data center is down, I want to have the default route to the MPLS router at secondary data center? My issue is if both MPLS routers in both data centers would advertise their default routes to the MPLS cloud if they both are configure as default-originate. Any thought?
2) If we want to 10 remote sites to advertise the default route to Primary data center, and the other 10 sites to secondary data center, how we set this up?
Any help would be greatly appreciated.
Thanks and Regards,
Joe

Hello, I want to create the VLAN on the switch and we need to have a big address pool of /22 bits. What is the advantage and disadvantage of /24 bit and /22 bits in a single VLAN? Please advise. Regards, Joe

Hello, We configured two subnets on the switch, one is for employee, one is for student. We don't want the student student access to the employee subnet. The DHCP server is setup at employee subnet - 192.168.100.2. We are not able to pull the IP address from the DHCP server at the VLAN20, but when we remove the "ip access-group 100 in" at VLAN 20, and it works fine. What ports should we open at the access list 100. Please advise. Thanks, Joe Int vlan 2 ip address 192.168.100.1 255.255.255.0 ! int vlan 20 ip address 192.168.200.1 255.255.255.0 ip access-group 100 in ip helper-address 192.168.100.2 ! access-list 100 permit udp 192.168.0.0 0.0.255.255 host 192.168.100.2 67 access-list 100 permit udp 192.168.0.0 0.0.255.255 host 192.168.100.2 68 access-list 100 deny any any

Hi Rick, Thanks for your help. We are running VPN over the Internet circuit and it is using eBGP as well as on MPLS cirucit. I' m not familar with Performance Based Routing. Do you have any sample configuration? Much appriciate. Thanks, Joe

Hello, Please see attched. There are two circuits, internet and MPLS that are connected to the router, and there is a LAN network 192.168.0.0/24 is connected to the router. Here is what we would like to implement. 1. The internet traffic (80, 443) goes to the internet circut. 2. The traffic FTP and telnet goes to the MPLS circuit. 3. When internet circuit is down, all internet traffic (80&443) switches to the MPLS cirucit. 4. When internet circuit comes back up, the internt traffic restores to internet circuit. 5. When the utilization of the MPLS circuit hits to 90%, it will use both circuts till the utilization is less than 90%, then the traffic of FTP and telnet only goes to MPLS cirucit. Any thoughts? I would appriciate. Regards, Joe

Hi we are using the profile of 10% Real time, 50/30/15/5/0 for QoS in the MPLS network, (COS1, COS2V, COS2, COS3, COS4, COS5)that means that we configure 10% for voice, 50% of remaining bandwidth for video, 30% of remaining bandwidth for critical data, and so on. •1. If we are in congestion in our network, and we have 15% of voice traffic (COS1), we know 10% will fallen into RT class, where the other 5% of voice traffic will go? Drops? 2. If there is no video traffic on COS2V, which class is going to use the bandwidth of COS2V? Are the COS1, COS2, COS3, and COS4 going to share the bandwidth of COS2V? or COS1 will have highest priority than the other classes to use the available bandwidth of CoS2V?, if COS1 doesn't take it, then it will be fallen into COS2? Please advise. Thanks, Joe

Hello, Here is my network topology. 1. Router 1 is connected to the Router 2 through the MPLS network by Using BGP. Router 1 has 100 MB. 2. Router 1 is connected to the Switch 1 within the same location by Using EIGRP. They both have gigabit ethernet connected to each other. I want to run redistribute BGP on the EIGRP on the Router1. Please see below. router eigrp 10
redistribute static
redistribute bgp 65001 metric 1000000 1 255 1 1500 Not sure if I should use " redistribute bgp 65001 metric 1544 200 255 1 1500" How can I identify the bandwidth for this redistribute? Please advise. Regards, Joe

Hello All- We have MPLS network via the BGP routing protocol. As you see the diagram, Site A and Site B have two links. 1. In Site A, the Link 1 is only allow 10.10.10.0/24 coming in, and 10.10.100.0/24 going out; In Site B, the Link 1 is only allow 10.10.100.0/24 coming in, and 10.10.10.0/24 going out. 2. Both Link2 to for all the traffic, expcet 10.10.10.0/24 and 10.10.100.0/24. 3. Also, we need to have reduandancy, if Link 1 fails, all the traffic should go to Link 2; If Link 2 fails, all the traffic should go to Link 1. Any thought? Regards, Joe

Hi Harold, You're correct. We have the default route in the DC. We tried not to addd the ACL's on the interface towords the internet, we may need to allow the subnet2 by pass through this internet because we may need to add the VPN as backup. So besides your recommendation, do you think the PBR is the best practice? if so, is the configur ok to go? Please advise. Regards, Joe
