Hi -
I have searched the archives but have not found an answer to my question
- is there any danger in using excessively high TTL values with
ebgp-multihop? For example, neighbor x.x.x.x ebgp-multihop
255 - 255 is generally much higher than needed, but is there
any risk/danger ?? Thanks in advance. -

The number of hops in an ebgp-multihop scenario
isn't usually the concern. When using ebgp sessions to null route baddies, the
peer can be an unspecified number of hops away. I would consider 255 to be
overkill, but not much harm. In normal routing, I would try to keep the hop
count within 1 or 2. It's just a good practice. Remember, every router between
the two sessions has to also know the route. Perhaps some of the older folks
have some better tidbits of advice.
