We will understand the BGP AS Override feature using below topology wherein 2 sites of a customer will be connected through an ISP. Scenario 1 In the below diagram a loopback 1.1.1.1 is advertised from SITE A and this update is forwarded by the ISP to customer remote SITE B. Since both...

When a server in the VXLAN BGP EVPN fabric sends multicast traffic to the attached ToR/leaf switch, the leaf switch forwards the multicast traffic within the fabric, as explained in the Cisco Programmable Fabric with VXLAN BGP EVPN Confi...
The protocol has to be set tobgp. The other protocol option islayer2mode (as explained in a previous section) which relies on the ARP protocol for IPv4 and NDP protocol for IPv6 to advertise the addresses. $ cat << _EOF_ | oc apply -f - --- apiVersion: metallb.io/v1beta1 kind...

Note: In the Cisco IOS and Cisco NX-OS software implementation, all the PE routers must have the same RD within the same VPLS domain. The virtual expansion (VE) ID, VE Block Offset, VE Block Size, and the Label Base (LB) relate to the advertised block of labels, as explained in the...
This occurs because the IP packet that carries the BGP update message has the DF-bit set and the IP MTU of 512 bytes used at the R2/R3 segment is lower than the IP packet size of 1116 bytes. As explained earlier, the reception of the ICMP message triggers PMTUD....
