Firewall mangle PBR: steering outbound path similar to inbound

Firewall mangle PBR: steering outbound path similar to inbound

Webinar
Packet-based routing (PBR) is a technique used to forward packets based on the contents of the packet itself, rather than just the destination address. It can be used to steer packets along specific paths or to apply different routing policies to different types of packets. One use case for PBR is to steer outbound packets along a path that is similar to the path that the inbound packets took. This can be useful in situations where you want to ensure that the return traffic for a particular connection follows the same path as the original traffic. To configure PBR on a firewall to steer outbound packets along a path similar to the inbound path, you will need to create a mangle rule that matches the inbound packets and marks them…

Internal BGP Tuning: Mesh Peering to Avoid Loop

Internal BGP Tuning: Mesh Peering to Avoid Loop

Webinar
In BGP (Border Gateway Protocol), mesh peering is a configuration in which all routers in an autonomous system (AS) are connected to each other via BGP peering sessions. This type of configuration can be used to improve the stability and reliability of the BGP network, as well as to reduce the risk of routing loops. One way that mesh peering can help to avoid routing loops is by allowing all routers in the AS to have a complete view of the routing table. When a router receives a route from a neighbor, it can compare the route to the routes in its own routing table to determine if it is the best path. If the route is not the best path, the router can ignore it and prevent it from…

BGP Tuning: Peer with Loopback

BGP Tuning: Peer with Loopback

Webinar
BGP (Border Gateway Protocol) is a routing protocol used to exchange routing and reachability information among routers in the Internet. One technique that is often used in BGP tuning is to configure BGP peers to use loopback interfaces. A loopback interface is a virtual interface that is used to create a logical loopback connection to the router itself. Loopback interfaces are often used as the source of BGP connections because they are always up and reachable, which makes them more reliable than physical interfaces. To configure a BGP peer to use a loopback interface, you will need to create a loopback interface on the router and assign it an IP address. You can then specify the loopback interface as the source of the BGP connection when you configure the BGP…

BGP Security Tuning: Pull-up Route

BGP Security Tuning: Pull-up Route

Webinar
Pull-up routes are a technique used in BGP (Border Gateway Protocol) to prevent routing loops. When a BGP router receives a route from one of its neighbors, it will "pull up" the route and compare it to the routes already in its routing table. If the new route is better than the existing routes, the router will install it in the routing table and advertise it to its other neighbors. If the new route is not better, the router will ignore it. Pull-up routes can be used as a security measure to prevent routing loops and protect against malicious or misconfigured routes. For example, if a router receives a route with an AS path that includes its own AS, it will know that the route has already passed through its…

BGP Troubleshooting: Route Origin

BGP Troubleshooting: Route Origin

Webinar
BGP (Border Gateway Protocol) is a routing protocol used to exchange routing and reachability information among routers in the Internet. When troubleshooting BGP issues, one thing to consider is the route origin. BGP routes can be either internal or external. Internal routes are those that originate from within the autonomous system (AS), while external routes are those that originate from outside the AS. If a BGP router receives a route from an external source, it marks the route as external and adds its own AS number to the AS path. This allows the router to keep track of which ASes the route has passed through. How BGP works on origin route? we discussed on this webinar series Webinar topic: BGP Troubleshooting: Route Origin Presenter: Achmad Mardiansyah (CEO GLC Networks) Please…

Steering Traffic in OSPF: Interface Cost

Steering Traffic in OSPF: Interface Cost

Webinar
Cost is the metric, OSPF uses to judge a path’s feasibility. Normally to adjust cost on a route you would adjust the cost value on an interface itself. This, however, affects all routes learned via this interface. Unlike the metric in RIP which is determined by hop count and EIGRP’s long mathematical formulated metric, OSPF is a little simpler. OSPF automatic cost calculation is an inverse function of bandwidth of an interface. As higher the bandwidth values of an interface, the lower the cost value. How to steer traffic in OSPF network by adjusting interface cost ? please note: we can only steer outbound traffic, we discussed on this webinar series Webinar topic: Steering Traffic in OSPF: Interface Cost Presenter: Achmad Mardiansyah (CEO GLC Networks) Please share your feedback or…

Tuning OSPF: Bidirectional Forwarding Detection (BFD)

Tuning OSPF: Bidirectional Forwarding Detection (BFD)

Webinar
BFD (Bidirectional Forwarding Detection) is a super fast protocol that is able to detect link failures within milliseconds or even microseconds.. All (routing) protocols have some sort of mechanism to detect link failures. OSPF uses hello packets and a dead interval, EIGRP uses hello packets and a holddown timer etc How it works? we discussed on this webinar series Webinar topic: Tuning OSPF: Bidirectional Forwarding Detection (BFD) Presenter: Achmad Mardiansyah (CEO GLC Networks) Please share your feedback or webinar ideas here: http://bit.ly/glcfeedback Check our schedule for future events: https://glcnetworks.com/schedule/ Follow our social media for updates: Facebook, Instagram, YouTube Channel, and telegram also discord See you at the next event Presentation slide [embed]https://www.slideshare.net/GLCNetworks/tuning-ospf-bidirectional-forwarding-detection-bfd[/embed] Recording available on Youtube [embed]https://youtu.be/zrCLXd5s4mM[/embed]   Thank you for attending our webinar!
