I'm trying to speed up BGP failover when we lose our primary ISP connection (either physical or BGP Peer). I came up with this configuration to match the diagram below. Will this work or is there a better way?NOTE - ISP #1 BGP Peer 1.1.1.1 NOTE - Rou...
I've inherited this network (see diagram).We have two Cisco 7604s connected to three ISPs. Router 1 has a 3GB connection to ISP#1 (eBGP neighbor AS#1). Router 2 has two 1GB connections to two ISPs; eBGP neighbors via AS#2 and AS#3 (see inserted topol...
Basically, will adding a new area (in this case, NSSA totally stub) cause a reconvergance in Area 0? I don't believe so but was asked to check by adding a new discussion. More details:1) The links to the new area will be defined as Pt-to-Pt2) The stu...
We have three ISP's connected to two routers. ISP1 has a 3gb circuit to our WAN router 1. ISP2 and ISP3 are connected to WAN router 2 (both 1gb).We have BGP to our ISP's; iBGP between the two WAN routers 1/2; and OSPF between the four core devices (t...
Thanks for replying so quickly! Regarding your request for an example of the network to be advertised via the NSSA: In area 0 we are currently advertising a /20 and in area 1 (NSSA) we are planning to advertise a /24 from that larger subnet. Does thi...
Yes, this is very helpful! I need to discuss with some of my peers in other sites and we will probably be making the changes you recommended very soon,
ignore my comment about the default gateway in the WAN routers. We are receving the full route tables from our ISP's and not just default routing to the vendor router(s).
In our WAN routers I do not see a default route in OSPF; even though the "default-information originate" is configured in ospf. When I "show IP route" the "gateway of last resort is not set"...when I do "show ip ospf database" I don't see a entry in ...
WAN router 2 (and WAN router 1) has a"default-information originate" statement in OSPF.The Core A/B switches also have static routes pointing to the loopback of the WAN routers (equal cost). so in the Core switches we see:Gateway of last resort is (W...
