## The Micro BGP Suite has a new utility: *peerindex*
|
||||||
|
|
||||||
|
I am happy to announce that *µbgpsuite* has a new tool in its arsenal, *peerindex*.
|
||||||
|
|
||||||
|
[peerindex](https://git.doublefourteen.io/bgp/ubgpsuite/src/branch/master/tools/peerindex)
|
||||||
|
is a simple PEER INDEX TABLE inspection tool documented in its own gorgeous `man` [page](https://git.doublefourteen.io/bgp/ubgpsuite/src/branch/master/tools/peerindex/peerindex.1.in).
|
||||||
|
|
||||||
|
When implementing *bgpgrep*, I removed any functionality not strictly related to BGP filtering dump,
|
||||||
|
this included the PEER INDEX TABLE inspection feature previously provided by *bgpscanner*, that is:
|
||||||
|
```sh
|
||||||
|
$ bgpscanner -f
|
||||||
|
```
|
||||||
|
|
||||||
|
This command used to display every PEER INDEX TABLE entry referenced by at least one RIB entry.
|
||||||
|
It was a useful tool to quickly recognize which peers populated a RIB dump.
|
||||||
|
|
||||||
|
*µbgpsuite* will get a dedicated tool for this task, the main topic of this article: *peerindex*.
|
||||||
|
|
||||||
|
In addition to showing only the referenced peers inside PEER INDEX TABLE, it can
|
||||||
|
also dump the full table as is.
|
||||||
|
|
||||||
|
> **Hint** -- as always, you can get a convenient PDF version of the manual page, like this:
|
||||||
|
> ```sh
|
||||||
|
> $ sed s/@UTILITY@/peerindex/g tools/peerindex/peerindex.1.in | groffer
|
||||||
|
> ```
|
||||||
|
>
|
||||||
|
> Don't you love man pages? ☺
|
||||||
|
|
||||||
|
Enjoy, and happy hacking,
|
||||||
