OTV COMMANDS on ASR1000
OTV running configuration
COMMON OTV MISCONFIGURATION
1. OTV adds extra overhead around 46 bytes which reduce the data throughput from default size of 1500 - 46= 1554. Since OTV sends all data packet with DF-BIT set by default, make sure end to end MTU is working fine else OTV adjacency will not come up.
2. For Unicast mode, adjaceny-server needs to configure on the server side and use-adjacensy-server needs to configure on remote side which will register with Adjacency server.
